Wii U WILL get a boost. In 2015

[Spade]

Smash will surely carry momentum into 2015 and there will be other games as well.
Zelda will push some units and hopefully Splatoon as well.

Edit: Was Wii U needs most in terms of games is variety. They need more from other different types of games. Ie) Yarn Yoshi won't push much, but games like Hyrule Warriors for Japan and RPG games will. Wii U just needs more variety. I've accepted the sales of the Wii U, so all I want are the games :)
