forest-spirit said: Only 23m left before it overtakes the DS.

And when that happens, it will be the right time to celebrate. It's like picking the right time to clap when at a special event, ball game or when someone is doing a speech.

Congrats to the 3DS, I expect another 10 million in 2013.

PSV is at about 1.1m. Turkish made a big celebration thread when it hit 1m, so justice was served.
