Because Sony bought exclusivity of MGS4.
Maybe future MGS or MG games would appear on other platforms, but right now I'm guessing Sony's got rights to the next few.
(Regardless of what Kojima thinks, Konami green lights, publishes, markets and distributes his games. They control him, he doesn't control them. So only Sony is preventing these games from being released else where and good on them for doing that, they're creating a competitive advantage for themselves).
