OMG!!! Smash Bros. just keeps on getting better and now that you can play as your Mii and use NFC figurines (which will also be compatible for MK8 btw) For 100 bucks you get Smash Bros., Gamecube adapter and a Gamecube controller so that's a sweet deal. Oh and just imagine playing MK8 as Link or doing a little Mario Party 10 as Kirby.
Bayonetta 2 now includes the first game and some Nintendo DLC stuff so now it's a must buy for me.
I'm sad that Xenoblade Chronicles X has been delayed to 2015, but it's better that they make sure it's an amazing game.
The new Nintendo IP Splatoon looks extremely fun and it sucks that we must wait until 2015

Mario Maker also looks quite fun as well as that new Toad game which I played and liked in Super Mario 3D World. Now we have unlimited Mario levels to play forever.
The new Zelda looks actually pretty damn good and the fact that it's open world and you can do any dungeon in any order like the 3DS game is awesome.
A new Star Fox game on the way is also nice and it looks like 2015 is looking very bright for the Wii U first party wise.
All in all I enjoyed what's heading our way for the Wii U and 3DS, but I'm also getting a PS4 now that GTA 5 has been confirmed.
