Metal gear solid 4

... is pretty much the only reason i really would like to get myself a console for, but I havent read up much about the exclusivity of the title.
Is this only gonna be available for the PS3 ... or will the 360 get it at some point a few months later?

Hmm, I'm really torn between choices now tbh .. PS3 is just too expensive for my taste, but there are sure a few games I need to play, uncluding MGS4 and Devil May Cry.
Even though the detail has dropped in the latest trailer, I'm sure it will be a stonking game.
