This is very import to nail down before 'reviews' for the game are done.
Sites like 1Up,EGM,Gamespot etc need to know either:
1) It's PS3 exclusive so they can trash the game with 7 or 8/10s with 'didn't live up to the hype'
or
2) There is some far off downgraded 360 port coming and give the game 9-9.5/10s with 'teh superior 360 version' getting 9.6/10s later on.
