The Nintendo 3DS sales information is in, and the numbers are astounding. 4.5 million units have been sold in the United States over the past 12 months, and the console was Nintendo’s best-selling in Japan in its first year. It's is also the best-selling Nintendo console in the U.S. as well, after initially being seen as a flop, resulting in a massive price cut soon after it launched. The price drop certainly worked, as the 3DS has even outsold the incredibly popular Nintendo DS, which in its first year sold "just" 2.3 million units. Have you picked up a Nintendo 3DS yet?
