This being a Final Fantasy game, I think we can expect a few new classes to show up. The safe money is on Summoner, Thief and Blue Mage, but it wouldn't shock me if Bard showed up in there as well. Why them? Well, mostly because of the way the classes are set out at the moment.
We don't technically have Dark Knight, but we have Marauder with mostly the same skills. We don't have Black or White mages, but we have Conjurer which is effectively both, making them also akin to Scholars. The point is most of the class roles are already filled in some form or another, so the new classes need to be fairly unique in their role.
We don't have a dedicated buff/debuff class, like Bards. Thaumaturge might be considered close, but their range of debuffs doesn't match the ones that used to be offered by Bards. We currently have no pet jobs, and summons seem almost a dead certainty given it's a Final Fantasy game so Summoner can fill that role nicely. Blue Magic is another staple of the FF series which hasn't been seen yet, so that's my reasoning behind that class.
As for Thief, we currently have no Steal or Mug skills, no Treasure Hunter, no Flee, and no sneaky combat. I feel it's absence like a hollow void. It might not have been a popular class in parties early in FFXI's days, but I adored the tactics of aiming those Sneak Attacks, getting the right timing so you could Viper Bite for more damage than was healthy for a level 40 job. I never really enjoyed melee jobs until I got my hands on Thief. It is, for want of a better description, brilliant fun.
So long story short, expect new classes which might easily include Bard. Personally, I can't wait to see what's in store for us.
We do have Steal and Flee right now... Although it hasn't been added in, Pugilist has an ability called "Steal" which does just that, swipes an item from an enemy. "Flee" has already been implemented in-game and is learned by Archer. It's called "Quickstride". Very useful for when enemies turn tail and run away from you. As for getting around, not so much... 30 second duration, 25-26 if you count the time it takes to draw your weapon, use it, then put away. It's on a 3 minute timer and usable by all classes minus DoH/DoL.
I don't have a link to it but an LS member had given me a list of jobs to come and sadly Summoner wasn't on that list. I do recall there was Shepherd (Which should be like Beastmaster in a way I think.) Fencer, Musketeer, Arcanist, and Bard was listed too. Most likely Arcanist and Musketeer will be the next two classes thrown in with the remainders being classes tossed in when the gates to Ishgard are finally opened.
