I think it will stay exclusive. and don't get me wrong 360 sales were pretty good for XIII but square enix should know at this point that anyone who wants the game will buy a ps3 for it. the game will still sell over 2 million with or without it being multi-platform. XIII on the 360 was done because of the 360's american install base yet ps3 sales were higher, which proves that an exclusive title will do just fine...but if the 360 gets versus then good for them they get to enjoy what looks to be an awesome game
