I don't see Nintendo doing particularly well off the back of their lineup; but better than 2013 for the Wii U seems odds-on. It depends on Mario Kart; if that can build up excitement, word of mouth and some sales and they get Smash out sooner rather than later to back it up; maybe even X and/or Zelda for the end of this year it could do relatively well. Sadly I see the other games doing nothing special in the long run.
Still far behind the other systems overall but reasonable compared to where it is now.
