Congrats, can't decide if I want an X1 or Wii U more...honestly shouldn't spend the money right now anyway haha!
I always thought about it this way:
If you want to play Nintendo exclusives - Wii U
If you aren't bothered about the Nintendo exclusives - X1/PS4
I wanted to play Nintendo Exclusives, especially Zelda and HOPEFULLY a new Mario game, so I had no second thoughts about a Wii U.
For games that aren't coming to the Wii U most of them do eventually come to the PC and I have a pretty capable PC so I shall get those games for the PC
At the moment, it looks like only Ubisoft have taken an interest in the Wii U and the games from them are actually quite good ports, everybody else (EA) have terrible ports from what I have seen.
The Indie side of the Wii U looks promising and from what I can see you can get a dev kit from Nintendo at very low cost, don't hold me to this but I think you may even be able to pick one up for free if you are a dev and can prove it.
