Why even buy the NX? I think you should wait another 5 years until Nintendo announces their next system after that.
In all seriousness; If you want to play Wii U games, get a Wii U. Simple as that. Sure you could play the waiting game, but who knows when they announce the NX and who knows if it'll be backwards compatible. Everyone's so worked up about that thing.
^ Exactly. You listed a great amount of games there with already an asounding library that the Wii U has to offer. And are you telling me that you're not hyped for Xenoblade Chronicles X?
