N-Philes and various forums are reporting the Japanese only Black, err, Graphite DS is being sold at the Nintendo World Store 
in NYC. The real kicker? Mario Inc. is charging $199 for the thing. Ouch! A wink, smile, and handshake from Miyamoto himself better come standard at that price.
Maybe we can get some additional color combinations this holiday season.
