Having spent a good portion of the last year casually playing through Persona 4 Golden on my Vita, the thought that Persona 5 might be not too far off sounds extremely appealing.
Atlus' parent company Index Corp. has just registered Persona5.jp, and the game has been in development for quite some time. Hopefully this means we'll be getting a better look at it soon.
The Persona series has consistently been some of the best JRPGs to come out over the years. While the Final Fantasy series has somewhat lost a lot of it's appeal, Persona has been right there to pick up the slack.
