In other words...
Resistance: Fall of Man, Motorstorm, Uncharted, Rachet and Clank.
Unreal Tournament 3 is coming to Xbox 360 soon
Burnout Paradise is also on 360
GTA4 is also on 360
Midnight Club LA is also on 360
Devil May Cry 4 is also on 360
DiRT is on 360 and is only out on PS3 in Australia as of now
So yeh... really you can't bash the Wii because PS3 1st party is not touching the Wii yet. No 1st party game for PS3 even has a 9/10 review average, Uncharted being the closest. Guess what games are? 3rd party games that are also on what? 360!
