I just saw this in the Persona tag on tumblr so just take it as a rumor and not fact. Thought I'd share it though.
"In the japanese theaters after P3: M finishes its credits, the crowd is treated to a trailer that theyve all heard was announced, everyone is hyped
Then the announcement reveals the same initial Persona 4: Ultimax Suplex Hold(dooo)
The audience is treated to the same voice overwork, slightly disappointed because all of them have seen it already, they know that its just the same trailer with what they would assume will have the platforms of the fighting game
Then it happens
Before the trailer reaches its conclusion and the unknown, Sho is seen, same pumped up attitude, same video
But then the trailer stops-
Sho is in the same pose for a few seconds
Then he moves in the same art engine as ATLUSs previous title, Catherine, looks in the camera, grins, and hopefully (but to your own preference) gives the audience THE most Engrish- quote:
Lets Go!
The Go then has a close up typography moment, turns into a
5
(The Audience has now died from the most awesome reveal)"
Sounds kinda legit but I'd hope Sho isn't the actual MC for P5, maybe just a side character acting as a bridge from P4A2 to P5
