I have gotten a even less likely character suggestion..if this game is not coming out till summer 2014 in Arcades..what if the final two charcters were actually from Persona 5 which we know is going to be announced very soon..maybe at TGS. They could promote Persona 5 by putting in two charcters from it into Persona 4 Arena 2..i am sure that ASW is working closely with Atlus so it's just an idea. Maybe Persona 4 Arena 2's story could lead into Persona 5..
