Which wii u game in 2015 will have the biggest first week sales(that isnt zelda)

[Bofferbrauer]

I do hope for Splatoon, but I'd say Yoshi's Whooly World or Xenoblade Cronicles X. Kirby is too Niche, Mario Maker probably too special, Starfox never sold very well and Mario Party on the decline.

Isn't also a Mario vs Donkey Kong Game coming to the Wii U?
