Nintendo adds third DS factory due to demand

Nintendo hoped they would be able to sell 1 million units of their new Nintendo DS portable game console in the US around the holidays.  Instead, 2 million pre-orders have flooded in, and in response, they have added a third DS factory in China.  While this won't fill the initial 2 million pre-orders, it will allow Nintendo to get 2 million in circulation within a couple months.  Nintendo now expects to sell 4 million DS units by the end of the fiscal year in March.  So who's left to buy the PlayStation Portable, which drops 10 days later in Japan?
