Since you actually are talking about games to buy, I'm gonna share what I'm gonna buy once I finally buy a Wii U 
Out of the released games:
- NSMBU + NSLU
- Nintendo Land (why not?)
- MK8
- SM3DW
- Zelda: Wind Waker HD
- DK: TF
- Pikmin 3
- The Wonderful 101
- Hyrule Warriors
I'd think about Sonic Lost World, Rayman and ZombiU as well.
The upcoming titles would obviously include Bayo 1+2 and later on the new Zelda, maybe Starfox as well.
Wii U is a GCN 2 - I called it months before the release!
My Vita to-buy list: The Walking Dead, Persona 4 Golden, Need for Speed: Most Wanted, TearAway, Ys: Memories of Celceta, Muramasa: The Demon Blade, History: Legends of War, FIFA 13, Final Fantasy HD X, X-2, Worms Revolution Extreme, The Amazing Spiderman, Batman: Arkham Origins Blackgate - too many no-gaemz :/
My consoles: PS2 Slim, PS3 Slim 320 GB, PSV 32 GB, Wii, DSi.
