They haven't even finished with the summoner job (said it most likely wouldn't be in at launch and implemented in first patch) and you think they are going to add a new class and job at launch on top of that? Possible, but highly unlikely. Don't get my wrong, I would love new classes. It's one of the main things I think the game is missing, but I don't think balancing out classes per city is reason to believe a new class will be at launch.
