Nah. If anything I think they all fell well below my expectations in terms of power. We haven't really seen what Wii U can do yet with proper optimisation and probably never will from third parties which makes direct comparisons impossible (that CARS game might be different though).
In the end I don't think it will affect Nintendo nearly as much as the fact that they pretty much abandoned a lot of their user base with the Wii. Clearly the ports of third party games at the end of the current generation haven't sold as well on the Wii U which leads me to believe that there is almost no audience for anything but Nintendo games on the Wii U.
It will take a lot of time and effort on Nintendo's part to bring their core audience back to the numbers it was once. I would say doing some deals ala Microsoft putting the Wii U logo alongside big third party launches, paying for advertising of third party games, and leading the way with first party games in genres such as FPS and TPS would go a long way.
In short: Power is not the real issue here. If third parties had good reason to port their games to Wii U and do it properly, they would.
