Put a fork in the Wii U, it is done. [Sensible discussion only, no flaming]

People just don't like the hardware concept of the Wii U, period. That's the main problem.

No one wanted or asked for another PS3/360 level console with a giant bulky touch pad controller that looks like a kids tablet. This is not appealling to hardcore players or casual players. 

The Wii didn't have that great of a lineup for its first six months either. Wii Sports was all people needed to be sold on the concept. And Nintendo fans got their Zelda, which was basically a recycled GameCube game. But other than that the library was basically sh*t for a long time until Metroid Prime 3 arrived the following August.

But the Wii was sold out forever. Because people liked the hardware concept (simple, get off the couch gaming with easy to understand Wii Sports that wasn't littered with Mario characters, but clean and simple looking Miis).

Wii had it. Wii U does not. I really think it's that simple.

The hardware needed to go back to the drawing board period, this is far worse than just a "oh they don't have Pikmin 3 and Wonderful 101 yet, but if they did, they'd be doing great!" problem.
