Why aren't there more PSP ports on the 3DS?

The most common answer is that 3rd party developers have a hard time competeing with Nintendo first party titles. There are a limited amount of games most people afford to buy (an attach rate of ten games per console is considered good). Of the 37 most sold 3DS games only 8 are from other publishers than Nintendo.
Shin Megami Tensei has a hard time selling on 3DS despite good reviews and frequently occurring sales (€10 digitaly in Europe).

To be fair, the numbers of JRPGs are usually great everywhere but Europe. We don't have here a big culture of JRPGs outside of the bigger ones (FF, Pokemon...).
