I will make the following bold prediction:
The Wii U will be discountinued sometime in 2015.
The Wii U will fail to sell more than 9 million copies by the end of 2014.
MK8 And Smash will be huge commercial flops. They will sell well below expections.
Zelda and other announced IPs will be moved to whatever console Nintendo releases next. Sometime by 2015 or 2016 at the very latest.
