This thread has gone so far off topic lol!
Anyway just to carry on the off topic thing, as sony is funding and helping KP and Konami on the MGS movie, I doubt very much it will come on the 360 for a long, long while. Also the money involved re-porting it to the 360, spliting the game down into smaller sections for the mulitple disks, lowering the audio quality and redesigning parts of the game i dont think would be worth it. Those who are concerened with PS3 game sales should stop looking at just the NPD numbers but the worldwide figures. For example DMC4 on the PS3 outsold the 360 version by about 200K ( roughly 20%), that is a "sony" game, GTA4 has about the same attach rate for each console with the 360 having a 1.5 million lead but with 6 million more consoles sold. As for MGS4 sales, well Ryan Payton will be happy, it looks like it sold approx 1.3 million copies day 1, and doubled PS3 sales for the week.
