They’re calling it P3P — as in Persona 3 Portable.
Atlus announced today that the PlayStation Portable port of Shin Megami Tensei: Persona 3 would make its way Stateside this summer.
Apparently, the developer is skipping over Persona 2: Eternal Punishment and Personal 2: Innocent Sin (which never got a US release anyway) in their PSP port series of the super-popular role-playing games.

Persona 3 PSP (or P3P) came out in Japan in November 2009. It’s an “enhanced” version of the PlayStation 2 original with the option to play through the game as a female character with altered story elements as a result. Also, the battle system is tweaked to more closely resemble Persona 4 for PS2.
