After several months of hints on the 3rd Birthday Twitter account, game director and character designer Tetsuya Nomura has finally confirmed that the original PlayStation series, Parasite Eve, will be coming to the Japanese PlayStation Store.
Not too many details were given, however, Nomura simply said that "A decision has been made for the [Parasite Eve] game archives. Details soon. Please wait for the official announcement." Given the speed of Square's previous PS1 game archives announcements to release, full details could come as early as the end of this week. Nomura did not say whether both Parasite Eve 1 and 2 would be heading to the Store, but given that he has mentioned the two games together in the past, it seems more than likely that they will.
Unfortunately for those living in the west, no information has been shared regarding an overseas release at this time.
