@Business guys: It's all business, yet Kojima has made games exclusively on Sony systems. Argument countered - while generally true, doesn't apply here very well.
@OP: Did you really have to make this thread? MGS4 is too old to matter any more, and the new game will be revealed soon anyway. Also, there's nothing stopping the new game from being multiplatform, especially with Konami putting pressure on Kojima. I do believe it's exclusive to a Sony system, however I don't think any other platforms are impossible either.
