Well, if none of the current games out right now interest you enough, I'd say you should wait. The second half of 2013 is going to have a lot more Wii U releases, so maybe getting one just before the holidays (so that there's a good chunk of games out, but Wii U's aren't out of stock due to it being the holidays) would be a good idea. Personally, I really enjoyed New Super Mario Bros. U and Nintendo Land.

NSMBU's level design is the most dynamic and hectic it's ever been in a 2D Mario game (with floors constantly shifting on you and levels loaded with enemies, even in the first levels), the challenge mode is really fun and difficult (I've still yet to get gold on all the challenges) with a big variety of objectives (the ones where touching coins kill you is especially hard), and mastering controlling Mario and the boost mode platforms at the same time really makes for a fresh, difficult challenge (quite a lot of challenges in the game require boost mode). Plus, it retains the 4 player co-op of NSMB Wii, which I'm a big fan of.

Nintendo Land is a lot of fun, especially in multiplayer. The games where it's all of the Wii Remote players against the Gamepad players (Mario Chase and Luigi's Mansion) are really fun, especially when everyone is talking and strategizing on how to get the Gamepad player. The ways the gamepad is used is quite unique as well, whether it's a dynamic camera and gun/bow aimer in Metroid Blast/Zelda Battle Quest, a Shuriken launcher in Takamaru's Ninja Castle, or an alternate camera view in Captain Falcon's Twisted Race (forward view for the TV, bird's eye view for the Gamepad, and you need to switch between both in different track parts). Some games aren't as intricate or content packed as others, but there's plenty of variety in the games.

Don't worry. All Wii U's from spring 2013 and onward include all of those first few month updates straight from the box, so all important issues have been ironed out regarding the hardware.
