It doesn’t seem like Atlus will be done with the Persona 5 universe any time soon.
Amidst all the speculation surrounding the mysterious Persona 5R, which currently is expected to be unveiled soon, owing to the activity surrounding the web domain publisher Atlus registered for it, here’s some more fuel for the fire. According to Persona Central, Atlus’ partner Ryu’s Office, the marketing firm that Atlus uses to make web registrations, has gone ahead and registered several more Persona 5 related domains.
These are “Persona5R.JP”, “P5S.JP”, “Persona5S.JP”, “Persona5M.JP”, “P5M.JP”, “P5B.JP”, and “Persona5B.JP”. These are a bit different from the Persona 5R activity we have been seeing lately (in that these domains are just being registered—the other domain has been registered with Atlus for a while now, and has now been updated, which suggests it is set to go live soon), but at the very least this all seems to suggest that Atlus isn’t done with the Persona 5 universe yet. Not when we apparently still have Persona 5 B, Persona 5 S, and Persona 5 M still to come (Persona 5 D just came out as Persona 5: Dancing in Starlight).
Until whatever these are end up coming to light (if they ever come to light), Persona 5 itself is out on PS3 and PS4 exclusively.
