Why no thread about this yet? They recently released a trailer showing game play. The only real story revealed so far, is that it takes place 10 years after Resident Evil, with Chris acting as a member of a group called BSAA and fills in the 10 year interval in Chris's life.

EDIT!
So far I understand its coming out on the 360 and PS3 at the same time.
