The IGN preview is up (
here) and one line from it caught my eye:
You'll also be assisted by a Battle Navigator, who can be issued commands via the Leadership Skill ability. (There's also a Labyrinth Navigator that will help you off the battlefield; both Fuuka and Rise can be assigned to one or both of these roles.)
I find it interesting that you can use both navigators to do different things in game. I'm not sure how much help a Labyrinth Navigator will be though, but that's the kind of thing one can only figure out by playing the game for yourself.
As for the chibi art style, I quite like it. It's perfect for a fun spinoff full of fan service, because it's familiar while being just different enough to distinguish itself. Plus, Soejima did a fantastic job of the chibi renders, so the art style has a good basis there.

Nope, chibi is not cute at all, cast lost their personalities and become generic as hell
I'm just curious, if you dislike the chibi style so much, why are you using it as an avatar?
