Well ,I dont see those games moving to the PS3 .Maybe Bioshock ,of wich some webpages as gametrailers and playfrance claim to have seen a PS3 build in action .But not for sure Gears of War . In any case ,if we go to first party product Sony outweights MS by a good degree . I mean ,MS has made great efforts and has managed to buy Rare ,Bungie and Lionhead ,plus they have some internal studies not many but some . But ,on the other hand Sony has like 100 programming teams all over the world as first or second parties .Just to name a few they have Team ICO ,Polyphony ,Guerrilla ,Insomniac ,Naughty Dog ,Incognito ,Evolution ,London Studios ,Zipper ,Santa Monica Studios (of GOW fame ) ,Sony Online Entertaintment ,Liverpool Studios,Ninja Theory ,Factor 5 ,etc etc ......the amount of games all those can produce is way bigger than Microsoft right now .
