well, the PS2 is sitting at 3.5m for the year, and the DS is at 17.4m for the year. Assuming some more sales for Nov/Dec push the DS 20m over the PS2 for this year and similar performance next year for another 20m units, I project that the DS will surpass the PS2 in total sales by Jan 1st 2011.
NOTE: all numbers based off of VGChartz sales numbers. If you want to go units shipped you may have to tack on another quarter.
