I haven't bought a new game since Super Smash Bros. so personally, I can go either way. I love new hardware and I definitely expect at least one successor next year, but as far as games, I could go either way. I don't need new hardware, but if Nintendo launches with Zelda and/or Metroid, yeah, I'd probably be all for that.
Thread related: this is an obvious choice so nothing terribly surprising here. Nintendo wasn't going to waste an opportunity to port a Pokemon game. People like Pokemon and there's a dearth of fighting games on Wii U. Makes sense.
