Sorry to disappoint, but I seriously doubt that the new outfit means we're getting a new job mid expansion. Yoshida stated that he'd prefer to make new jobs for each expansion pack rather than doing it mid patch cycle since making new jobs takes a lot of time (it was in one of the live letters I think but I can't remember which one).

I believe Rouge/Ninja came out mid cycle because those jobs were cut due to 2.0 being pushed out to meet the deadline.
