It's not going to be made for the 360, because Kojima said due to the size of the game you'd need about 8 discs. It only fits on one disc for the PS3 because it's blu-ray. New-gen consoles are another story though.

So who knows? It may just be the Legacy Collection (MGS4 inclusive) for the PS4 and Xbox One.
