Ok, for the sake of argument PS2 will have ~140-5m shipped while they continue to slowly sell systems 1m/year for who knows how long. The DS is at 127m. If we assume they reached ~30m for FY2010. Let's assume some doomsday numbers for the following years.
20m FY 2011 (launch of 3DS & down 10m units YoY. GBA dropped a few million the year the DS launched)
10m FY 2012 (GBA halved the next year, however this number is higher than the GBA in the equivalent year)
5m FY 2013 (GBA was still selling decent too)
DS total = 163m
So just this year alone should be more than enough to surpass the PS2.
