Famitsu has a brief interview with Katsura Hashino from the Persona team. Hashino told the magazine he’s concentrating on the "next numbered title" right now. Persona 5 is making steady progress and Shigenori Soejima submitted sketches for the game.
Hashino also teased an announcement saying he has a collaboration that will surprise everyone, but that announcement is far off.
Persona 4 Arena, which continues the storyline from Persona 4 and ties in characters from Persona 3 is out now.
