It wont have that kind of support even leading the hardware sales .
Look at it this way ....X360 software for february 180 millions ,PS3 software 97 millions ,Wii 130 millions .So creating a cross-plattform game for PS3-360 gives you access to a 277 million-a month/(and growing ) market plus the PC data and creating it for the Wii a 130 million business mostly dominated by Nintendo .Of course you can create some friendly game as Guitar Hero III and sell loads of games ...or churn out some low budget games and earn a lot of money.Or ports from the PS2 ,DS or PSP .But in the way of original high-budget games for the plattform ...I dont see that happening anytime soon .
