Canon announced the 7D. But don't let the nomenclature fool you. This is not a successor to the 5D Mark II, it replaces the 50D. It has a smaller APS-C sized sensor (wasting what your good glass can see) and is under $1,600.
In video circles, it's going to get some serious attention though, because it can shoot 1080p/24. I'm not sure how to feel about that. Recording to H.264 is weird at best. AVC-Intra is better though, even if it is a Panasonic variant.
What I really wish Canon would do is a firmware update for the 5D Mark II to do 24fps. That would certainly make the indie film folks happy.
