The same day it chose to announce the 3DS, Nintendo officially hit a ridiculous milestone for the existing DS platform(s) in Japan: 30 million units sold. Enterbrain estimates that, through March 21, the handheld has sold 30,030,434 units. The last reported worldwide total, in January, was around 125 million. Unsurprisingly, the best-selling game is New Super Mario Bros., with 5,767,262 copies sold.
