They said they won't do 2 dps again. Since EW had sage, one new job will very likely be a tank. As for dps, either caster or phys ranged. Considering that NIN doesn't share armor stats, I would bet on phys instead of caster, but I wouldn't be surprised if they changed stat sets - there would be 5 tanks sharing same armor, they might as well make all 5 melees do the same. And when it comes to geomancers, beastmasters and others, recently they said they are considering adding something new, instead of taking jobs from other FFs. Lastly, considering they said on multiple occasions that pets are nightmare, beastmaster seems very unlikely, unless they make each beast just fancy effect, like SMN.
