Depends on how the sales for the next week and the week after that is. Can't really say to what level the sales for both consoles will drop at this point.
No matter what, if it's only for this game, it only has a shot for 1 week, nothing more, and even then it would need to be relatively close to the xbox already, unless HUGE amounts of people are buying a PS3 for this game (I know of two to three, but that's marginal)
