let's see release dates for America : Pikmin 3 August 4, New super luigi 3 ( retail ) august, Wonderful 101 in September, Wind waker HD in October, Donkey kong country Tropical freeze in November, Super Mario 3D world in December
+ sonic lost world & Batman Arkham Origins in October iirc + all them Ubisoft games like watch_dogs, rayman, splinter cell, and assassins creed 4 are releasing on wii u too ...I don't see the problem ..Wii U's line up is PACKED for this year.
Next year I see them releasing bayonetta 2 early like january or February like how Bayonetta 1 released in January, I see Wii fit U being a early title for next year same with Yarn Yoshi and + there's other 2014 games like X, Fire emblem x SMT and smash bros..don't forget E3 where nintendo will show off more new games
in early 2008 Nintendo released the 1 2 3 punch in the first half. they released smash bros brawl in March, mario kart in April and wii fit in May ..if smash bros is really that deep into development ( i very much doubt, i see smash as their big holiday game ) they could do the same strategy again
