There was no third job. The special event at the end of the second night was a concert by the Smash Brothers (The butchered every FFXI song they played and were told to get off the stage by quite a few people) and one member of the Star Onions who did and amazing job playing the Mario theme (I'm serious), 2 songs we already know and 1 from WotG.

Everyone was hoping that they would just sneak a video in at the end, but it didn't happen. Unless they just put it in the game and don't tell us until we see it in the manual tomorrow, there will just be DNC and SCH. Don't worry though, DNC rules.
