I really think it's Wii U. 3DS has a few things, maybe another small game pulled out from their sleeves, but Wii U should win this poll. Tomodachi Life and Hoenn remakes are the only 3DS games by Nintendo I know that are coming out. Wii U has X, Zelda U, Bayonetta 2, Smash Bros, and a bunch of other secrets, like Miyamoto's new IP. If that doesn't get you hyped for Wii U I don't know what will.

Wii U has X, but 3ds has Pokemon and a few other stuff i'm still looking forward too :D

Well, the hype for Pokemon is real. I'm all for voting the 3DS xD

X and Super Smash Bros. for Wii U sure generate some hype. (even though they have no official release date lol) Also, there is Pokemon Alpha/Omega... Nintendo isn't placed too badly. I'd still say Wii U.

Bayonetta  

Wiiu no contest for 2014 by the looks of it

You do realize that 3DS is also getting Smash, right?

If X actually comes out this year, then the wii u will win...

WiiU.

But now the Ruby and Sapphire remakes have been announced, it's getting very close.

Wii U
