Meh,I'm bored and I have nothing to do. Didn't mean to ruin your fun,but you were holding false hope there.
Eh, I wouldn't be surprised if they did this anyway in real life since they already put Metal Gear Solid II on Xbox.
Well actually after Kojima(the guy who created MGS) ported MGS2 on xbox he said he wouldn't port any other game. Because MGS2 on Xbox sucked...badly. So he doesn't believe in porting games. Furthermore,there are some things in MGS4 that can only done with the PS3s hardware. And MGS4 is going to be like 50gig. So a double layered Blue ray disk. Putting it on the 360 would mean dividing the game into like 5 Dvd9s... Yeah,I did a little research >_>
