Yeah, I'm not sure why Nintendo released the Wii U (and the 3DS) so soon with really no good games. I'm going to buy a Wii U (just like I bought a 3DS) but I see no point in shelling out $300 for a system that I'd just play one or two games on (New Mario Bros 2 and maybe Monster Hunter 3: Ultimate) until the rest of the games that I want to play come out.
The 3DS had exactly the same problem, it launched with no games of note and for the first 6 months or so of its existence its flagship title was a remake of a game from 1998. Now it has a large selection of excellent titles, Super Mario 3D Land, Fire Emblem: Awakening, Mario Kart 7, Tales of the Abyss, Animal Crossing, Luigi's Mansion, Kid Icarus, etc. but for the first year, there were really no reasons to buy it.
