The NES/SNES days were a different era so you can throw that right out the window.
The Wii never had NSMB, Rayman, Sonic, DKC, Mario 3D World, as its core releases in such rapid succession ... there's not a lot of variety here because the library doesn't have much in other genres, outside of the party/dance games most of the main content for the Wii U is platformers. Even the Wii early on had far more variety -- Zelda: TP as an adventure game, Metroid Prime 3 as a FPS, Wii Sports as a party game, Super Mario Galaxy as your platformer, etc.
GameCube first year similar thing -- Luigi's Mansion, Smash Bros. Wave Race, Star Wars Rogue Squadron II, Resident Evil REMake, Super Mario Sunshine, Pikmin ... all different genre types.
Wii U ... NSMBU, Mario 3D World, NSLU, DKC: Tropical Freeze, Sonic: Lost World, Rayman Legends, Zombi U, Nintendo Land, Pikmin 3, LEGO, Wii Party U, Game & Wario, Wii Fit U ... lots of overkill with platformers and party games.
Also brace yourself for historic lows on many Nintendo IP, NSMB, DKC and Mario 3D World are almost certain to be the lowest selling in their respective franchises. Maybe DKC:TF can beat DKC3.
Even GameCube was selling far higher than the Wii U is right now providing a better market for something like Super Mario Sunshine than the Wii U is to 3D World. It's a shame.
