Well, this year they have Yarn Yoshi, X, Fire Emblem x Shin Megami Tensei, Super Smash Bros., Donkey Kong Country Tropical Freeze, Hyrule Warriors, Sonic Boom, Mario Kart 8, a new Miyamoto IP, and Bayonetta 2. And those are just the announced ones. Coupled with Wii Sports Club, Wii Party U, New Super Mario Bros. U, New Super Luigi U, Nintendoland, The Legend Of Zelda: Wind Waker HD, The Wonderful 101, ZombiU, Pikmin 3, NES Remix, Sonic Lost World, and Mario & Sonic At The Winter Olympics, there will be a lot going on for the Wii U.
I've had mine since last March and haven't been bored with it at all. I enjoyed getting the 30 cent classic NES and SNES games and Earthbound especially. It has been a great purchase.
