My (current) dream camera would use the same 8mp 1.3x crop CMOS chip as the 1DII, smaller buffer, slower FPS, fewer pro firmware/menu features, smaller body size (10D size), weather sealing, 45-point AF, and priced somewhere between 1DII and 10D.
It doesn't need to be a tank for pros, but it'd be nice to have the seals to match my lenses and a decent AF. Alas, I'm guessing that Canon's going to stick to 1.6x crop factor for their amateur/semipro cameras though, even though the new chip is a nice size and resolution...
