Saw this over on NeoGaf
In less than two years the Nintendo 3DS has surpassed lifetime sales of the GameCube, 2/3 of the N64 and nearly half of SNES. Interesting...
For reference, it took the 3DS around twenty months while the Wii did it in around sixteen months (but the Wii had two holiday seasons compared to one and a half for the 3DS). That should put LTD worldwide sales for the 3DS at somewhere around 22 million.
