I think 3DS can beat it. Here is the totals that vgchartz has them at for each region.
3DS
North America-12.98m
Europe-12.02m
Japan-14.72m
Others-2.59m
Total-42.31m
PSP
North America-21.38m
Europe-24.14m
Japan-19.92m
Others-15.26m
Total-80.70m
3DS will likely pass PSP in Japan sometime in 2015. I believe it will pass PSP in America as well in the long term. Maybe not in Europe and def not in Others. Overall I imagine 3DS passing it by a few million.
When the herd loses its way, the shepard must kill the bull that leads them astray.
