3DS has sold 19 million units to date worldwide
As for quarterly sales, Nintendo typically issues a list of games that sold at least one million copies in the period. This list usually includes a lot of "evergreen" games, like Wii Fit, New Super Mario Bros. and Mario Kart Wii. Surprisingly, for the quarter that ended June 2012, only one game made the list: Pokemon Black Version 2/White Version 2, which sold 2.45 million copies, including 30,000 outside of Japan – despite not being released outside of Japan.
