In December alone, Nintendo sold more than 2.5 million of their popular handheld and more than 2.3 million of their home console. For those taking count, that brings the lifetime U.S. sales of both systems at 47 million for the DS and 34 million for the Wii.
Now, granted, the release of Kinect and PlayStation Move haven't quite hit their stride, so only time will tell how much market share both motion gaming peripherals will take away from Nintendo's lead. In addition, Microsoft experienced console shortages in the months of November and December, temporarily halting the 360's surging sales in the fall. Still, as reports from NPD have suggested, sales of the Wii have started to dwindle month and after. 2011 will surely be a real test for Nintendo with Kinect and Move gaining much-needed momentum.
