Has anyone managed to get excited about the Wii U since its launch? I certainly haven’t, and new sales figures for Nintendo’s console seem to suggest no one is.The latest figures coming out of market research company NPD Group actually suggests that video game sales in the US for January have increased compared to January 2012. But what isn’t mentioned is January this year was a 5 week month, where as last year it was 4 weeks.Gamasutra has been kind enough to do the adjustments, which in turn shows sales have actually fallen as a whole across the industry. But the news for Nintendo is particularly bad. Estimated sales of the Wii U console amounted to just 59,000 units. It could even be as low as 45,000 units.To put that in context, no current gen console has sold that few units in a month it has been on sale. Ever. Even the worst months have seen better sales than that. Nintendo’s own figures also show how interest in the console has fallen drastically. Sales of the Wii U $789.00 at Amazon from launch until the end of 2012 amounted to 890,000 units. To fall to just 59,000 units the following month must surely have alarm bells ringing inside Nintendo.Software sales are also pretty dire, with every game released on both the Wii and Wii U selling much better on the Wii in every case. That’s to be expected due to the huge difference in user base, but the Wii U ownership isn’t exactly growing fast to catch up.As usual, Nintendo’s success rests on the games it produces internally, and if these hardware sales figures are accurate, they desperately need a hit and a system seller. We know that a new Pikmin and Luigi game are scheduled for release at some point this year, and Nintendo has promised to show off a new 3D Mario game and Mario Kart for the Wii U at E3. I can’t help thinking they need some guaranteed hits sooner than that, though, or something to spark interest like a (big) price cut.If sales continue at this pace the installed base will be comparatively tiny when the PS4 and Xbox 720 make an appearance.
