Spoilers for P4:A but not really, if you listen to the bombcast
Persona 4:Arena seems to be a great set-up for persona 5. If that's the case, the cast of great characters from persona 3 and 4 will return in 5.
The only question is: How much would you pay for every reference, spoken or writen, of the imposter ''Yu Narukami'' be replaced by Charlie Tunoku?
I would put down 10$ for DLC that did that, how about you?
