Wow, the staff is kinda surprising. Mitsuru Hirata is the chief director and game designer, Eiji Ishida is the development director and chief battle designer. Both are Atlus game design vets, so the system design should be pretty great. Zero concerns about the battles being really fun. Apparently they're going to be introducing non-Atlus staff working on the game after this, so we'll find out who the outside collaborators are soon.
