4 million for 2015? They have no big sellers for 2015 like Mario Kart 8 or SSB, not happening.

This isn't Kirby canvas we're talking about. This is smash. Smash is definitely something and it's 2 or 3rd best system seller for Wii u. In fact it's the main reason I want a wii u. Same for many people
