Nearly a month ago to the day, Sony triumphantly proclaimed that it had sold its 50 millionth PlayStation Portable. Now, Nintendo's making that figure look awfully small by shipping its 100 millionth DS handheld. The number includes original DS, DS Lite and DSi systems, and clearly, those sales are still going strong. The original DS launched way back in late 2004, while the totally hip DSi is slated to ship here in the United States in under a month. So, who's taking bets on how long it takes to hit the magical 200 million mark?
