The 40d with 1.3 crop is the most unlikely rumour i have heard for quite some time.
It's pure and 100% speculation. Don't let anyone fool you into believing that this is anything outside of the What If Realm. Canon could do it. Will they? We don't know.
The speculation is based on official words from Brian Worley, dSLR product manager for Canon Europe, who said that Canon will eventually move to full frame, except for entry level. That means that, sooner or later, the xxD series will drop EF-S compatibility. That may happen with the 40D, then again, it may not happen untill the 50D. Maybe the xxD line will morph into another market segment and disappear in its current form, who knows?
Like any format, APS-H size has its pros and cons. What makes APS-H so interesting is that it is the biggest size that can be produced in single lithography passes. Anything bigger needs multiple exposures per layer. So for a large volume price-competitive market segment, like the prosumer xxD range, it would fit well, because it's the biggest slab of silicon that can be made relatively cheaply. It's a sweet-spot, production wise, 50% bigger in area than APS-C.
Moving to APS-H would definately differentiate the 40D from all the rest of the 10 Mpixel prosumer cams like the D80, D200 and K10D. It would also prepare a lot of users for the full frame for the masses future that is said to come.
Yes, it'd kill EF-S for xxD. That will happen at some point anyway. I'm not too impressed by the argument that the EF-S line is important to Canon. Other than the 10-22, 60 Macro and 17-55 IS the majority of the EF-S line-up consists of kit lenses.
So what is the distance between the back of the lens, and the mirror? For years Konica built 35mm SLR cameras where the film to flange distance was 40mm, the shortest in the industry, the mirror actually shifted back while going up, so that there was clearance. This kind of technique might also work for Canon, so that a 1.3 crop or even a full frame might be able to use an EF-S lens.
