I know some say dancer is a long shot being added, but I honestly think it will be announced, we've had a lot of quests being added revolving around dancers, the ul'dah one specifically mentioned the class and needing to master it,
I could see it coming off of puglist though hope it doesn't as then it would be fist based, much prefer it comes off a rogue duel wield type class
So my own personal predictions, whether they happen or not

Is musketeers for archer
Thief, ninja dancer being grouped
And possibly a red Mage off of conj and therm
