Well I'm not drawing any conclusions yet since there are more important things to worry about in life. But I am curious - in general terms - as to the source of your info Whayne. How did you come into possession of these specs?

I was told last year that canon was working on a curved sensor design & redesigned lenses to match with a new mount.

More nonsense. You could not economically fabricate such a sensor from silicon. Chips are flat, sliced from wafers which are sawn from highly purified silicon ingots. You can't easily saw a cylindrical or spherical slice. Full-frame sensors require steppers that expose two or three masks for each layer. That is hard enough to align on a flat chip. Canon would have to invent not only a new sensor, but a whole new chip fabrication technology and chip plants. Large new chip plants have a capital cost of $400 million to 2 billion dollars. Canon would have to invent new steppers, and new tools to build new steppers.
It's hard to imagine Canon inventing a polymer sensor with the same pixel pitch and dynamic range and other favorable characteristics as current sensors. It may happen in time, but not this decade.
I don't think there is any great advantage to a cylindrical or spherical image field. There would have to be a huge advantage to cause Canon to abandon a line of lenses.

I agree, it doesn't make sense. On the other hand, they would be great for shooting pictures of concave brick walls
I was told that this would add more image area to the chip and allow for more MP with larger photosites, plus part of the lens design limits is designing it to a flat field when it's naturally curved allowing sharper lens designs to be possible.
This is what I was told & modifying wafer board to be curved just seems like an added step, not a need for a whole new plant.
Like I said, I was told this over a year ago. Seems like a possible step in Canon's sensor evolution, but who knows. I'm not a camera designer, I just play on on TV.
SuperPeter provided accurate info on the last 30D release. But if what he says is true, then this is likely to be a yawner. Probably the same 8MP, 2.5", Picture Styles.

I would guess that what is being referred to here is in fact a flat sensor with microlenses designed to accept light from an angle, which I believe is possible - there is some such arrangement in the Leica, I seem to recall.
They are called off-set microlenses, and deal better with lens edge issues.

I know everyone is having great fun with this post but in reality, if you look at their history, it is about the time frame for a new 1Ds. What better way for them to come out with Digic III with their top of the line camera. Everything else is too new to change.

Lots of 1D mark II's and original 1D's for sale on the Buy Sell Forum. People are getting their cash ready for the new body....
Bet we will see many more bodies come up for sale soon...

yeah, my long-standing prediction has been that a ton of people will sell their 1DII's and 1DSII's for rather low prices like the week before the show/announcement- then they'll be buying them back a month later when nothing outstanding is released!!!
I know, its soooo cliché to think that every aussie has a pet Kangaroo, and we all ressle Crocodiles for fun!
The last roo I've seen was laying dead on the side of the road!
Girl, boy, kangroo, goat, sheep, what do I care. Only applies if he needs a real life instead of spending his time making up rumors which I am sure isn't the case, right?
I have been wondering a lot about the 30D.
Why did Canon actually make it? It doesn't make much sense. It's almost identical to the 20D even though 1,5 year has gone by.
Perhaps as a tester to see what makes people upgrade. Lots of people said that it wouldn't be selling a lot. I actually though so too (thought that most people would be changing their 20D's to the 30D or perhaps their 10D's if they was more conservative). But I guess not. As far as I have heard to 30D is selling plenty, actually all that Canon can produce (that's what I have heard, - but I know these kind of rumors comes in all different flavours).
But then again, - their just have got to be a simpler, cheaper and more than anything safer way for Canon to do that. Looking back it actally started half a year earlier, - with the 1D mk IIn being just a minor upgrade to the 1D mk II.
For a while Canon has (with success I might add) sold cameraes in a clear cycle. First a high end camera comes out (e.g. 1Ds), then comes a prosumer with the same technology but cheaper and with smaller sensor, less features etc (e.g. 10D) and finally comes the consumer version (e.g. 300D). Between any two cams are 6 month. So one camera is replaced after 3x6 months = 18 months.

2002-09 1Ds First DIGIC processor, starts out at high end and goes down
2003-02 10D
2003-08 300D

2004-01 1D mk II First DIGIC II processor. Again it starts out at the high end
2004-08 20D AND 1Ds mk II
2005-02 350D
--
2005-08 1D mk IIn AND 5D. NO digic III, Actually 1d mk IIn is not much different from 1D mk II. The 5D is a new platform. Canon listened and produced what people asked for, - a not to expensive full frame.
2006-02 30D When the 1D mk IIn didn't change much their just isn't much space for the 30D to change.
So what does that say? I guess that the Digic III platform just wasn't ready for august 2005 and/or Canon was pretty sure of their market lead and that they would still have people upgrading.
Í will comment a bit more below, - first like be make some predictions.
My prediction
2006-08 350D replacement, - not much better than 350D, - or if Canon is as clever as I believe I am (or something like that) perhaps a 350D replacements and a 3000D-series camera.
Who knows, the legend could be a totally new 3000D-series camera.
2007-02 1Ds MK III. Will have DIGIC III and be a true improvement. How it will be better is hard to say, - but ISO 6400 and higher MP is my guess. Other possibilities are higher Dynamic Range, in body IS etc.
We might also see things like WLAN etc.
The way I see it they are upgrading often to make people change often, - just like the CPU's, graphic cards etc. development are pushed hard to make a demand.
Even windows are sold this way (except for some very long delays that Microsoft are very sorry about and at least some of us custommers are actually pretty happy about. A 5 years lifespan of the XP is much more economical than a 3 years lifespan). Of course with hardware it's a bit harder, bacause we much more need/want the improvements.
But fact is that even the D30 made a lot of people very happy.
Interesting to speculate on, but I guess the future will reveal it self, - once it's ready and not really any time sooner than that.
