A thought about the square sensor:
36x36mm sensor would need same sized focusing screen, which must fit between the mount and the shutter. Is there enough space for it?

I donīt know if it was already published here but in CAMEX , Netherlands it has appear briefly in its web page announced the new Canon 1Ds MkIII by 13.300 !! > $17.000 two days ago.
The link is reflected in Northlight Web Site with some screen captures.
Do we know it appeared briefly, or has someone just photoshopped the page?
If true and 35mm, it doesn't seems that it could be a bayer camera at that price. The U.S. price would more likely be 13,999 or 14,999. We get a discount as the Japanese feel sorry for us having an idiot for a president.

I heard Canon leaked an announcement, in Asia, of the 40D. My camera salesman told me to wait on buying another DSLR for a few weeks. What that means... I don't know. So I asked about EF-S lenses, he said, "They're dead in the water, they're going to FF. "They're" could mean Canon or the buying public I didn't really know how he meant it and I didn't want to ask. He's a Nikon shooter so I kind of thought he meant Canon.
Your "information" is bogus. You heard wrong and your source hasn't thought it through and is not connected.
First, the 40D "leak" was a hoax, as explained in the main thread, where this stuff belongs anyway. It had zero zip zilch "specs" anyway.
Second, EF-S lenses are not "dead in the water". That is so laughable. Canon's best selling DSLRs (plural) are optimized for EF-S. They have excellent reviews. Canon has invested R&D in them and continues to make profit to recoup that investment. The fools who have claimed that EF-S is dead in the water right from the beginning still claim it and will be claiming it years from now when EF is replaced. However, there is a fair chance that EF-S may outlive even EF.

A new body line that does not accept exisiting lenses in any way does not seem like it would be a big seller if EF bodies could take old and new lenses........
With all the discussion going around about MF and whether Canon is going to change mounts, etc. I'm going to float an idea:
One of the current problems with digital is light fall-off in the corners. This is currently handled, partially, by microlenses. However, for digital SLRs, unlike film SLRs, there is no reason for the "film plane" to be flat.
What would happen if they introduced a new line of SLRs with a concave film plane; each sensor tilted inwards so that the light entered at the optimal angle? Naturally, all EF lenses are designed to focus on a single plane, so we'd need another line of lenses designed to be sharp at the sensor.
The mirror, viewfinder and autofocusing mechanism would need to be modified; the shutter might too.
(Hmm, I see some difficulties manufacturing a curved sensor. Wonder if those are too difficult to overcome?)
Anyhow, this is well beyond rumour, and solidly into wild-ass blue-sky dreaming, so we'll return you to your regularly scheduled debate about whether to they are going to merge the 1-series cameras (given the Northlights' rumoured $17K price, perhaps they're just going to include both models in the same box -- thus everyone would be right :-)

Has been discussed before. What I remember is that, it is possible but the investments in new technology, mfg. process and re-tooling would be so high that no fabricators of wafers would dare to do it unless there is a larger market than just image sensors.
But you know that there are 35mm-format Wide Angle lenses that have very little vignetting; right? Contax 21 is a good example.

If they have better loseless compression and/or fast buffer to handle 22MP at 20fps, why bother have two 1-Series in Canon lineup?

Perhaps the microlens assembly could be fabricated to have the individual lenses arranged to present a general concave shape at the front and be flat in the back to mate up with a flat sensor.

E.
Why does this myth persist? It's been shown a zillion times on a zillion forums that vignetting is no more a problem on FF digital than it was with film.
I see a lot more vignetting in my film shots than I do from my digital shots. Of course that could be because I used K25 most of the time and had to use larger apertures than I do with digital.
Nevertheless, I can flat out guarantee that neither Canon nor any other company is going to be wasting any R&D money on a solution to a problem that they believe does not exist.

Canon has a patent for replacing the microlenses on a sensor with 'light diffusing medium'. This will serve multiple purposes - it will supposedly reduce the cost of a sensor by 40%, achieve an effective 100% fill factor, and reduce the effect of light fall-off.
I don't know when they are going to introduce a sensor with this technology but it's very promising.
In the gas clouds of Jupiter live large gaseous life forms, which have a "word" for themselves that sounds like something like "LGooo" if the vibrations of their emanations are normalized to fit into the normal hearing range of humans. In order to sense their environments they live in symbiosis with very interesting microorganisms (micro by our standards, anyway) which behave as sensory apparatus for their LGooo host. The principle role of these little creatures is to intuit, using their highly evolved psionic capabilities, the desires of their hosts, and using similar clairvoyant abilities outline a sensory depiction of the region of curiosity in the manner with maximum emotional impact. If the object or situation of curiosity is extremely dangerous, the microsymbiotes present a stunning and fearful image with all the important factors clearly delineated, so as to impart both urgency and knowledge of the situation so that proper action may be taken. Likewise, if the object is one of affection or aesthetic interest, the microsymbiotes present it with extreme beauty and clarity.
What Canon's engineers must do is contact the LGooo and propose an extraction of small numbers of their microsymbiotes, perhaps in exchange for Neon or other similar noble gas (the LGooo's favorite snack), or halothane (commonly used as anaesthetic on earth, and their favorite recreational stimulant). The microsymbiotes are so attuned to the fine structure of the universe that they can place computer-readable images directly into the memory of compact flash cards (or any other media, including paper or canvas for direct-to-print capture), of arbitrary resolution and in any format imaginable. Canon must simply provide a container of suitably high pressure and with the right gaseous nutrient composition to which a CF card may be attached (for example in an external pouch - there need be no electronic interface). The microsymbiotes, which are approximately rat sized, will sense the intentions of their human companions and imprint images with maximum impact directly onto the nearest flash card, once a suitable training regimen has been imposed. The user will only have to provide the microsymbiote with fresh pressurized methane once per week.
Suggested retail price: $25,000. No lenses required. The LGooo have a sophisticated inter-system transport network which could probably be leased to Canon to provide cost-effective shipping of the product from Jupiter.

Are you all that unhappy with your current gear that so much is demanded/wanted from Canon? Do you all have that disposable income to replace a perfectly fine lens with a new one that is only slightly different? Or upgrade a 1D series to a new one? I mean daydreaming is one thing, but owning $20,000 worth of equipment or more is absurd. Just curious...

Now here is a man that understands rumors. Did he mention the 30D? I think not.

I have about $70K in gear. What catagory is above absurd?

Why would it bother you if other people want to and can afford to upgrade their equipment? I don't understand this rationale, yet I see it day in and day out on these fora. People want something better than what they have, for whatever reason, and if it available and they can afford it, they can certainly buy it without any justification to you or anyone else.
What kind of car do you drive? People buy 30 or 40 thousand dollar cars every day, and do they NEED this kind of vehicle for basic transportation from point A to B? Of course not.
Why people feel the need to press their own personal feelings about camera gear on everyone else is amazing to me. If you are happy with your gear and never want to upgrade anything, that's great. Suggesting that everyone else OUGHT to do the same as you is ludicrous.
You are expressing a personal BELIEF. It is not some golden standard, it is a personal preference. Trying to impose it on others is what's absurd.
Guess what? I have a 1D Mrk II N and 4 L lenses. When Canon announces their new 1-series, I may either get THAT, or get the 1Ds2, and keep the D2N as a back-up. Right now I'm waiting to see what happens before I decide, but I WILL be getting another really expensive camera. I'm also planning on adding a 500 f/4 L IS, maybe a 300 f/2.8, hopefully a Contax Zeiss 21 2.8 distagon (if I can find one), and most likely a 135 f/2. If they upgrade the 100-400 to a constant aperture 4.0, I'll also upgrade that lens.
And I'm an amateur. A rank amateur. I take snapshots, but hope to become a great photographer with training and practice. And I can't WAIT to upgrade my gear, Because I Can and I Want To.
And I would never say ANY of this in public if it were not for the Gear Nazis who demand that everyone remain completely satisfied with every piece of equipment they currently own, and put an upper limit on the worth of equipment any one person should ever own.

No, allas, that's a "Houston, we have a No Go".
Some little russian stealth company has obtained the licences on the LGooo technology and holds it hostage for several billion US$. So, while you are right on the money, the... well, the money involved makes it a bit of a problem.

If you're a professional or a well-heeled and devoted amateur, there is nothing absurd about any amount of money you feel like spending.

The difference between light-falloff towards the corners in film vs. digital is minimal - both are subject to the same physical laws of optics (cos ^ 4) from which the majority of light falloff (optical vignetting) is derived.
Van Walree does a good job of describing the effect:
