Am I disappointed that there aren't more games for the system, especially more big games from Nintendo? Sure.
Am I disappointed that I bought the system in the first place? Not at all.
Why? Because between the good retail games that ARE there, and the sheer amount of content available digitally on the eShop (many of which, both VC and indie, you can ONLY get on eShop), I am a satisfied gamer. That does not mean that I do not wish there were a few MORE big retail titles. But surely, if this Zelda game comes even remotely close to living up to it's potential, then that alone will make the system worth it.
I still do not think they will put out the NX next year, as so many people seem to be assuming. They will show it OFF next year, that does not mean it will be out before 2017. Iwata said shortly before he passed that they were committed to giving Wii U owners their money's worth. And I believe that will be the case, with many more retail games between now and 2017. Iwata dying is not going to change that, people like Miyamoto and his other friends in the company will not let it.
So for NOW? I'm content with Wii U. And if Zelda is any sort of amazing? Then I will be HAPPY with it. Either way, I'm not sorry I bought one.
