this is the problem with PS3, most 1st party/exclusive games are not sold very well
this year examples:
-Socomm
-R2
-LBP
-Motorstorm
-Valkyre
can we imagined >4 exclusive games, with sales not as high as it hope to be,
funny thing all game with rather bad sales are the one that have demos
hope KZ2, will have different fate.
i think sony better stop KZ2, if they confident, just don't put KZ2 demos
just like Halo3 , GeoW2
