During Nintendo Conference 2010, CEO Satoru Iwata announced the Japanese launch date and price for the upcoming 3DS handheld.
The portable will release on Feb 26, 2011 and retail for 25,000 yen. The two launch colours are Aqua Blue and Cosmo Black. Prices vary by market and it's tough to say that the price will be exactly the same in other territories, but that amount is equivalent to approximately $300USD/€220/£190.
Iwata also said that North America and Europe will get ahold of the new hardware sometime in March of next year, with details to come from their respective Nintendo branches.
