After launching in late February in Japan and late March in the West, Nintendo's 3DS has topped 10m units globally through the first full week of December 2011.
Through December 10, 2011, global 3DS sales are in fact just over 11m units. The system has been available for 37 weeks in the US, 38 weeks in Europe, and 42 weeks in Japan. If we used those same number of weeks by region for other platforms over the last decade, we can see that 3DS has been performing rather well since its price cut, although even with the cut the launch pace is still not quite historically fast. Figures below are aligned sales in the same number of weeks 3DS has been available from launch.
