PSP is selling more than DS due to two reasons, IMO:
1.- Backwards compatibility: 3DS has it, VITA not (physical medium)
2.- The PSP-VITA cost difference is much higher than the DS-3DS difference.
It doesn't make much sense to buy a DS (you can play the complete catalog with a 3DS) but it makes sense to buy a PSP if you want to buy cheap 2nd hand UMDs
