Sometimes miracles
The problem is they keep relying on motion controls. The Wii U game pad made for an interesting idea that next to nobody used.
A lot of fans would probably just as soon have a SNES 2 than the successor to the Wii/Wii U. The Wii was a revelation that quickly died out (as evidenced by the now defunct Waggle and Kinect). Kids (and adults) don't want to have to aim by standing up, they just want to use their thumbs. The novelty is gone. It's not a bad thing to have but its time is past.
And, as evidenced by Star Fox, reliance on motion controls is a huge turnoff. The option is nice to have, but not something that should be necessary.
I don't know. I see what you're saying, but Nintendo made a stupid amount of money from the Wii. It was a massive success. The WiiU, not so much.
