IGN has estimated that Nintendo has sold about 4.3 million Wii U consoles worldwide to date. An unnamed source who’s apparently close to the NPD Group has told the website that 222,700 Wii U consoles were sold in the U.S. in November. To reach its goal of selling nine million Wii U consoles by March 31, 2014, Nintendo needs to sell at least two million systems per month leading up to the end of the company’s fiscal year. Earlier this month, however, several analysts predicted that Nintendo will fail to hit its Wii U goal.
