Thought not a lot of info on the R10, I think we have something to go by:

Is it coming? - YES
Fullframe? - YES (as a minimum)
AF lenses? - YES (and fast)
Fast buffer? - YES (same Maestro image processing system as in the S2)
Take manual R lenses? - YES, that too.
Leica simplicty? YES (just look at the lack of buttons on the S2)

From that we can guess:
It's going to be 24 MP or more (based on the 37,5 MP in the S2, reduced to size 24x36 would be 24MP)
Coming into existence summer 2009 or later
Same Kodak sensor, hence quality, as the DMR
Not a heavy camera
Probably less noisy than Nikon and Canon
Will be shaped after the highly popular R9 body, but much smaller

And one more thing. M9. They are working on that, too.
