Wii was a huge gamble but a total success. Wii U was another gamble but they lost. I think the name and terrible marketing had more to do with it's failure than the Wii. I mean it def is also failing due to lack of power but there are so many reasons it is failing and it has nothing to do with the Wii which was a huge success. Personally I think the nunchuck controller is the best possible controller for gaming. I love it and I hope their next system uses it.
