I love all these comments making assumptions about the Japanese markets with no facts or citations to back them up, way to go guys.

and now for the most uninformed post on this board, brought to you by Lil_villain2kg. "360 fanboys will say xbox can run mgs4 but the truth is it cant or it would have been developed on both systems...it wasn't necessarily an exclusive but the developers want to take it to the next level and the only way to do that is on the ps3" Congrats you win the prize. But seriously, if you think exclusives are ever decided strictly by hardware limitations, you are wrong, if you can post any links to back up your claim that would be helpful.
