Although GTA IV will be available on both the PS3 and the 360, if you want the "complete experience," you're going to have to go the Xbox route, or so says Rockstar's Hosi Simon in an interview with Games Radar.
His reasoning is that, although the games are identical, *IV'*s extra content--downloadable episodes--is a 360 exclusive:
GTA IV will rock regardless of which version you pick up, but if you have the choice, how are you not going to go with the version that gives you bonus content? I find it baffling that Rockstar isn't throwing the PS3 owners some kind of bone.
