The enhanced Persona 2: Eternal Punishment PSP port hit Japan last May, but now we're seeing some hints that it might be making its way stateside at some point. A rating recently popped up on the ESRB (Entertainment Software Rating Board) website, listing Eternal Punishment as a Teen-rated title.
Since the rating lists Persona 2: Eternal Punishment for PS3 and PSP, a PSN release for the latter is likely. Among the RPG's enhancements is a new animated intro by Madhouse (actually, nevermind, this is the PSone version), which we posted on the day of its Japanese release. We'll be sure to update as more information surfaces regarding a western release.
