The ridiculously titled Bravely Default: Flying Fairy will use a job system similar to Final Fantasy V, according to a report by Dengeki Online (as translated by Andriasang).
You'll get to use two types of abilities: Job Commands—active skills you can borrow from either your current job or one you've used before—and Support Abilities, which are passive skills like +10% HP or Cover. Those skills will be limited based on a "cost" system that sounds a lot like Final Fantasy IX.
Bravely Default will also have party skits not unlike the Tales games.
There's no word on a U.S. release for this 3DS role-playing game just yet, but it'll be out in Japan this October. Square Enix will likely give us localization news closer to then.
