This isn't Canon EOS, but might be of interest to those looking for the most image quality possible in a DSLR.
Hasselblad has two crop format DSLR's the H3D 22 and the H3D 39 with 22 and 39 megapixels respectively. As with most camera manufacturers they have used their form lens mount but cropped the sensor from 60 mm x 60 mm to 36 mm x 48 mm. Most manufacturers other than Canon have a problem with angle of incidence of light in corners of digital sensor when the sensor is made the same size as a film image.
Now Hasselblad is calling the 36 x 48 mm sensor full frame an have introduced a new crop camera, the H3D 31 that has a sensor that is only 31 mm x 48 mm and has only 31 megapixels. Hasselblad considers that the 22 and 39 mp cameras are mainly for studio work, but the new 31 mp model is for mobile photographers and will be the camera of choice for professionals who have been using 35 mm digital SLRs. Guess who makes 35 mm digital SLR's. You can count the manufacturers on one finger. Of course the H3D 31 is competitively priced at only $24,000 US. (Since the price is only about $16,000 more than a 1Ds Mk II and there are about 16 more megapixels, you can think of the additional cost as only being about $1,000 per megapixel or $.001 per pixel. Who can't afford a tenth of a cent a pixel?)
Also of interest, like Canon with their EF-S lenses, Hasselblad has now introduced a 28 mm lens that can only be used on their digital cameras.
