It's actually pretty terrible considering the system is $50 cheaper, has a better bundle, Mario 3D World, DKC: TF, Zelda: WWHD, Wii Fit U, Wii Party U, Wii Sports Club, Rayman Legends, Sonic: Lost World, Pikmin 3, and a second wave of Call of Duty/Assassin's Creed/Batman/Just Dance games going for it this year.
No momentum at all.
The notion that things like X, Bayonetta 2, etc. are going to have a serious impact on hardware sales where DKC and Pikmin 3 and Wii Fit U haven't is also very (very) unlikely.
