I own a 7D and a 50D before that. The difference between them is a lot smaller than people think, so a conventional 50D update would be squeezing into a very small gap. So given that we do have a 7D, doing something a bit different with the 60D is a logical step for them to take. Apart from the tilting screen, it remains to be seen what else they have done. Fast AF in live view would be my wish - and a good complement to the tilting screen. It must be possible, just give their firmware engineers double strength coffee for a while. Look at the improvements in the E-P1 AF by firmware since launch until now, it far better than 7D.
Side note: you might be asking why I'm using live view AF on a 7D - the short answer is that it gets around the aperture limit of phase AF, for example when using teleconverters. MF isn't fun on that combo.

Of course that is NOT possible. Put a 3/4rds lens on the micro 4/3rds cameras... an notice the slower (if at all) contrast detect AF.
EF lenses are designed to work with PD AF commands from EOS cameras.
All contrast AF exchangeable lens camera manufacturers have started a NEW lens range with NEW lens mount for contrast AF.
Sony does not even bother to implement ANY AF with A-mount lenses. Samsung doesn't use the Pentax mount lenses either.
