Predictions made by gamers concerning the current Nintendo line up of games.
Pikmen 3= Little Bump to nothing. (Got Little Bump)
Wind Waker HD= Won't sell anything (The explosion happened here and at one time 4 Wii U games was in the Amazon top 100)
Super Mario 3D World= Won't help at all looks cheap. (Currently the most sought after Wii U game and continuing the Wii U increase.)
