I would be happy as long as it is Persona and is an RPG, not another fighter. P4G2 is fine by me, I love that cast and mythos and would be happy to reunite with that cast once more. Persona 5 would be just as amazing tho, new cast, setting, theme, mechanics is really exciting.
What I cannot forgive is if any facet of the announced exclusives is exclusive to 3DS or WiiU. At that point I will call boycott and not buy another Atlus title until the wrong is fixed. I don't care how chummy Sega is with Nintendo these days, Persona is very much a Playstation thing, most of the fans reside on PS systems. PS3/Vita(maybe PS4) or BUST!!!!
