I can't beleive Wii U was able to go from 2,000 to 50,000 in Japan. It's a Christmas miracle!
It also shows 3D World's sales. This game should be at 800k+ on the next update, and 1 million by the end of this year is practically gaurenteed. New Super Luigi U might also get 1 million by the end of the year, counting digital sales.
