I'd say Mario Kart 8 is my most anticipated WiiU game at the moment, followed closely by X and Smash Bros.
I'm also excited for Bayonetta 2 and I'm interested but cautious about Hyrule Warriors.
Still hoping for some mention of Yarn Yoshi, Shin Megami Tensei X Fire Emblem and Zelda U. But they are not going to release in 2014 :P
