APS-C and Mirrorless. That is a good idea. Jut hopeCanon can do a fast AF. I should come with its own line of lenses to keep the size small. Also Canon should provide the Ef/EF-S and Leica M mount adapter.
A lot of those who lurk around CR would like that. However, we swim in a small pond, and probably are not representative of the boarder market. The other problem with making a camera like this small is that with the flange very close to the focal plane, light will be hitting the sensor at a very oblique angle - especially for short and fast lenses. Leica has already dealt with this, and I think patented the associated micro-lens design. It would be a lot of R&D effort for Canon to do something similar to satisfy a relatively small market - hence the costs could be very high.
