If you clear away the fanboy-isms on both sides, the PS3 drive is just a little slower than the 360 one. This is pretty much a non-factor in most games, including those that stream. The reason it's an issue at all in Oblivion is the odd way it loads the game data in chunks instead of streaming the way GTA always did. So it has a unusual need for a high number of duplicate data. If it had been made for the PS3 in mind, this wouldn't have been an issue.

If MGS4 would work on the 360 I think depends a lot on what Kojima plans to do with all of that space. MGS2X was a lazy port, so I think we can set that aside. I mean, Konami can't possibly be that lazy anymore, can they?
