sorry, but what's the big deal about weather sealing. ...I know what it is! I just don't think that it is going to be a large selling point for this level camera. I'm going to go out on a limb here and say that if Canon actually allowed us to vote for one or two new features for this camera e.g. APS-H, 3" LCD, Live view, 6+ FPS, ISO 6400, larger VF, or weather sealed. I think weather sealing would fall to the bottom of people's wish list. ...but people talk about this feature as if this one thing is going to define the camera over the 30D or D200.

I'll tell you what. Nikon D200 has it, Pentax k10d has it - that makes for almost all of the competition. Canon is falling behind in features (no in body IS either, but that's understandable because of the IS lenses - but nevertheless, competiton has it).

If the competition had, say, downloadable ringtones would Canon also have to implement it?
The point is that a feature may not be a deal-breaker. Weathersealing is nice, but you need sealed lenses too. The fact that the competition has feature X doesn't automatically make it a must-have.
Canon absolutely should add weather sealing to the 40D. I think it is a big mistake to leave only the competition offering weather sealing on this level of camera. It won't cause me to switch, and I most likely will be upgrading to the 40D with or without, but for new users this is an area where Canon will be lacking on the spec sheet.
I don't think downloadable ringtones or other fluff is a fair comparison. Weather sealing is something that is functional, and adds definate value to an SLR.
If Canon really wants to make the 40D a hit, they have to offer something that will set it appart from the 30D and the others (D200, K10D). I am hoping for a upgrade like the 10D to 20D upgrade was. Adding a few megapixels is not really a upgrade, it's just bringing the camera up to the level of the competitors. Anyways, I think Canon will not make any big upgrades for the 40D, which will help the competition get even further. If they want to set it apart from the others, 5D AF/ 6fps and Weathersealing are must IMO. 10 Megapixels is fine and enough. 12 would be nice, but I highly doubt it. We'll see if Canon will loose some more shooters or not. I also hope they've been reading these topics, and those from January/Feb, and understand what we shooters are expecting from them.
IMO 12 mpix wouldn't be nice since it would decrease IQ (in terms of noise levels at high ISO and DR). I really don't know why the hell would an amateur need such high mpix count. I'm sure that over 95% will never print larger than 30x45 cm and for that 8 mpix is good enough, not to mention 10. And more more thing: will most of the amateurs switch to L glass and top of the line prime lenses to be able to handle all that resolution? I doubt it. And keep in mind that 17-40L, like a butter knife, just doesn't cut in this case. 12 mpix on APS-C is like 30+ mpix on FF. Is there a lens in Canon lineup, that can handle that?!?!?!?!
Hear hear! 12 Mpixel on APS-C ? Just see how Nikon's D2X(s) manages to get 12 Mpixel from 1.5x crop. It's definately hitting the resolving power of the lenses out there. Canon's 1.6x crop will be even slightly worse.

Why not 12mp with a new sensor and crop 1.3X! Less noise, more IQ. It has been talked about.
I know, no EF-S but it would help the resolution/mp problem.
I guess I would rather see 10mp with the same sensor but wouldn't the noise go up?
For me, the only reason the higher mpix is useful is when, due to a less than perfect action opportunity, you would like to crop the image (and print the result). I do some sailing photography, and my 6 mpix rebel (so old!) has held me back in this regard more than once.

If they had a 12MP 1.3 sensor wouldn't they have put it in the 1dm3? Forget 12MP, the cost benefit wrt noise isn't worth it - and the camera above and below the 40D are 10MP. ISO6400 and great 1600 would be far more beneficial to the masses than a small increase in resolution. All those great and inexpensive f/4 telephoto lenses (whose f/2.8 cousins are twice as heavy and orders of magnitude more expensive) would become effectively f/2.8 themselves. Now THAT is a feature that would kick butt, considering the competition struggles to get "good" ISO 1600 as it is.
About a year ago on dpreview, I made an 'observation' about lack of weather sealing in the 30D and basically got shouted down with arguments about how we shouldn't expect Canon to provide such sealing in this level of consumer camera...
I bought the 30D when it was first available for £999 in the UK. That's a thousand pounds of high tech electronics, designed to be used outside that doesn't offer basic protection.
The keyboard I'm typing this on, just like yours, has a membrane between the keys and electronics designed to avoid disasterous coffee spills etc. I have a calculator on my desk which has a similar membrane, yet cost about £5. Why you need a sealed calculator is anyones guess, but it's there. Yet apparently it's unreasonable to get similar sealing in a thousand pound camera. What gives?
And before anyone says otherwaise, I DO use the 30D in appaling conditions with great confidence - nothing has ever gone wrong with it. And no, weather sealing isn't a deal breaker at all. But that doesn't mean it shouldn't be there as standard on every DSLR.
PS - I couldn't care less what the 40D specs are, I'm happy with the 30D. But unfortuantely I think it's going to have 12MP...

My kind of thinking
But **IF** Canon moves the xxD series to APS-H, then they have their advantage over D80/D90/D200/D300/K10D/K20D right there. Better ISO, better DR because the sensor is bigger. Then they don't need to bump the resolution another notch anymore.
And personally, I'd prefer to see 10 Mpixel APS-H with ISO performance like the new 1D Mk III rather than moving to 12 Mpixel and have less stellar high ISO performance. But that's just me.
Nikon's 1.5 crop offers approx 10% more surface area than Canon's 1.6. Would EF-S project to a slightly larger area? I'm not suggesting the 40D will be 1.5, but maybe in the future...
EDIT:
A 10MP, 5fps APS-H 40D (or maybe the 50D?) would be the smart move for Canon in 'my' opinion, and price it about the same as the D300 - but in order to do this they'd need a xxxxD below the 400D which also has an EF-S mount.

12 Mpixel * (1.5)² = 27 Mpixel full frame equivalent
12 Mpixel * (1.6)² = 30.27 Mpixel full frame equivalent
If we know that the 1Ds Mk II already needs high quality glass in order to avoid bumping into the resolving limit of said glass then it's safe to assume that the 10% difference in sensor area for 1.5x/1.6x crop will be of very little practical difference.
Spec's are posted many places Google "Canon 40D" It looks to be 10mp that sure is a let down, since the rebel is 10mp ...and bigger back screen for the money..
it better have something to offer other that a new name Unless you just have to own the latest model !
