For Persona fans, Innocent Sin has always been the missing link in the series. Although North America received the Shin Megami Tensei: Persona 2 - Eternal Punishment, the follow-up set in a parallel existence, Persona 2 - Innocent Sin was never ported due to unexplained reasons.
Atlus' remastered version for PSP is expected fall 2011, and will include new quests and the choice between the original and remixed soundtrack.
