The list is incomplete. Here goes, 2014 WiiU Games:

Super Smash Bros
Mario Kart 8
Project X
Bayonetta 2
Shin Megami Tensei x Fire Emblem
Project C.A.R.S.
Puyo Puyo Tetris
Skylanders Swap Force (Japan)
Project Nova
Wonder Flick
Cryamore
Gunlord
Liege

Still, most of those games don´t have a launch date yet.
Child of Light
The Lego Movie Game

Like I mentioned elsewhere, I was listing what I thought would be "big sellers" in both years. I doubt that Puyo Puyo Tetris applies.

Now that DKC : Tropical Freeze is delayed, it changes the problem, that's right. But even before, I think 2014 is better, at leas in terms of quality games.

Nintendo is hardly working on Super Smash Bros 4 to make it a perfect game (some adjustments/rebalancing for characters compared with SSBB, skid bullshit disappearance, better effects, better music (if it is possible), better graphics, better all :) ). I hope for new features.

I really enjoyed Mario Kart 8 trailer at E3. The graphics are really good, and it shows some evolution on the series (f-zero like), which is not unpleasant. A return of Double Dash snaking is good too.

X game really enjoyed a lot of Xenosaga fans and we can hope much of this game.

Nintendo also did a great job co-financing Bayonetta 2. I want to see what they can do with this franchise.

Unconfirmed 2014 games such as Zelda U, Yoshi Yarn, Mario Party 10, Shin Megami Tensei Cross Fire Emblem, unconfirmed intelligent system game, unconfirmed other koizumi game should also delight gamers.
