Seeing as it's a new Nintendo console, and considering I skipped on the 3DS just so I can have more money for the Wii U, hell yes I will be buying it! Probably get the deluxe, cause I like to show my gaming superiority with the sleek black look.
As for the games: Definitely picking up NSMB U, Pikmin 3, Monster Hunter Tri Ultimate, and Rayman.
Maybe (pending reviews): Assassin's Creed 3, Zombi, Wonderful 101
