I'm already at the point in the Wii U's life, that I will strictly be using it for Nintendo games and handful of 3rd party exclusives. As long as Nintendo keeps bringing out some of their quality games, I will not regret the money spent on the Wii U. That said, I haven't touched my Wii U since beating ZombiU. Really a shame that it's looking like Wii all over again, minus the insane install base. It's going to be much more difficult for them to build momentum from 3rd parties at this point without some big news.
I'm not even sure a price drop would even help at this point, because I haven't heard anyone I know ( this forum excluded) say "The Wii U is too expensive", but moreso that there aren't any good games, the games are too expensive for too long (opposed to PS3/360 versions), and probably the majority of them not even knowing what it is/confusing it with Wii still.
