Re: Wii failed NOT
Calling the wii a failure is dumb. if you say that, you're bad and you should feel bad. This is a console that made more for its maker than any other in its generation, and still gets use years later. It got our parents to play games, hell our great-grandparents to play games.
The problem with the wii U is that nobody who has a wii needs one - they're still using the wii just fine to play the games they like, the component video is plenty good enough for the cartoony graphics that work well in those games, and the hardware was pretty bombproof (if you didn't throw your wimote through your monitor). Does wii sports bowling HAVE to be in HD? I don't think so, it looks good enough on a 50 inch set with the right cable.
Anyone who wants games in HD probably has an xbox or a playstation too, and there's no reason to upgrade both, especially with the cross-platform developers dumping the wii ports.
I would love it for nintendo to survive, because they do understand how to make games fun for everyone. But it's going to be rough sledding for a while.
