You people talk shit about the wii but guess who won the last console war sales wise? The Wii did.
Systems sold:
Wii - 99.84 million
PS3 - 77 Million
Xbox360 - 75 million
So with WiiU being backwards compatible and offering NES, SNES and N64 games still; while being cheaper, the WiiU may win this cconsole war. If the Steambox doesn't dominate..
Also heres a console coming out later this month called
Ouya which runs on its own version of android. It was funded by kickstarter and will only be 99$ I believe. All games are free to try amd the entire console is open source or rooted for customization. Its basically a cheaper Steambox...
