The game industry as a whole in is kind of a strange place right now, though all three consoles in general are probably selling decent enough I've noticed a lot of 'meh' reactions out of people including myself, I purchased the Wii U, but even then I had less enthusiasm compared to previous consoles I've purchased in the past. Not to mention the AAA industry doesn't seem to know how to effectively evolve and seem to be taking nearly everything in the wrong direction with unnecessary burden on players with unnecessary complex measures to ensure proper system operation, anti-piracy measures that don't work, and the industry increased paranoia over used games. As games continue to go higher and higher in cost, many AAA publisher completely disconnected on what they can realistically make off titles, and the increase number of games getting release not only on consoles but also other mobile devices as well...
Honestly, I have to say it's not a particularly pretty picture at the moment. It's not just Nintendo, I think quite a few developers are heading into trouble.
