I'm guessing this is through October 2006 for the DS and February 2013 for the 3DS. 24 months tracked by NPD for both. Kind of misleading as the 3DS has likely fallen behind at this point in mid april (or mid December '06 for the DS). The DS did 2.518 million in November and December. It also did 1.233 million in the first three months of 2007. In comparison, the 3DS did 317-340k in Jan/Feb, and VGC has it at 120k in March for a total of 437-460k.
After that point it likely won't be much of a contest. The DS was cracking 400k in nearly every month of the year, sometimes even 500k. It also did 4 million across November and December. That's more than the 3DS did in the full year of 2012.
