Nintendo 3DS is STILL doing better than PSP. NX will screw its chances on beating PSP.

The differences between the PSP and the 3DS are very important to make that comparaison.

-The PSP came during a time when handheld devices were all the rage, plus it was one of the best multimedia systems around. The 3DS has to compete with all sorts of other portable competition (mobile devices, tablets...) and it's very limited compared to those, it's definitively not an adecuate multimedia device.

-All PS devices have really good support, even after their replacement. Also, the Vita didn't inmediately take off, so those sales still went to the PSP. The 3DS almost had the same problem, but they manage to cut it quicker. If they hadn't done that, the DS would have reached and surpassed the sales of the PS2.

-The PSP was very easy to pirate, and I'm sure that sold the hardware to a lot of people. The 3DS doesn't have that "advantage".

-PSP had a lot of 3rd party support thanks to the healthier handheld market of the time. The 3DS has a good support too, but not nearly as much as the DS-PSP times.

Considering how hard the mobile market has damaged dedicated handheld gaming, I'm happy to see the 3DS still selling as well as it is.
