The longtime whispers of MGS4 coming out on the 360 have been smushed by a Konami rep, who says that it is indeed a PS3 exclusive and there are no plans to develop a 360 version. People thought that even with epic sales it would be impossible for the team to break even, given the enormous development costs of this gaming juggernaut. Thus the rumors were born and propagated — perhaps a later, expanded 360 release?

But no! The “sources” claimed by XboxFamily are clearly in error. Guns of the Patriots will be exclusively on the PS3, if it ever does come out.
