Update: I’ve been informed by Nintendo of America that this is for amiibo rather than Wii U hardware sales. The source Games Beat/Venture Beat incorrectly reported this.
VentureBeat has confirmed today that the Wii U has now sold over 11 million units worldwide since it launched back in 2012. The news came as part of the NPD figures which cover North America, but clearly the 11 million is worldwide.
