>>70>As for Kaneko, I highly doubt it, he seems to have taken a less hands-on position higher in the company.
That doesn't mean he will never work again as a character/monster designer for another Megami Tensei game.
I don't think he will come back for a Persona or Shin Megami Tensei game, but I can't see a single reason as to why he couldn't come back for a spin-off title.
