The most recent issue of Hong Kong magazine GameWave apparently claims that Revelations: Persona is being ported to the PSP in Japan. Atlus has not yet confirmed or denied the rumor.
Revelations: Persona was released on the PlayStation in 1996. The game centers around a group of high schoolers that battle demons using magical Personae.
The Persona series has since gone on to spawn numerous sequels, including last month's Persona 4.
