Ok......difference here between Wii and WiiU is that casuals, the main target of the Wii, dont care about graphics. Core gamers, the main target of the WiiU......care about graphics. I keep getting this feeling that the WiiU will have no home.
Casuals will be put off by the tablet controller (aka more complicated then extremely simple Wiimote controls)
Core gamers will be put off by the specs being current gen. If Nintendo doesnt care about what MS and Sony do, then listen to your own fans.
