In ARR, your current class is determined by your current weapon. Since we know that there are no existing classes that use 2 daggers (GLA may use a single dagger sub-20) nor is there a class that uses a gun, it can be easily inferred that they will be new classes. Furthermore, it helps that Yoshi has actually said that they're going to be classes.

I seriously doubt we're going to get a gunblade class/job mainly because it's such a specialist weapon (the only gunblade users are extremely high ranked Garleans and we're talking about a sword with a built in gun; I can't imagine many of those lying around) while also being mostly the same as one of the existing weapons (you know, the sword). There are plenty of other weapons we're much more likely to see (like hammers/maces/clubs, flails, whips, and 2h swords) before we get a gunblade *if* we ever get a gunblade class. In fact, there's already a gunblade in game (Blazefire Saber from the Lightning event) so I'm pretty sure that any other gunblades we happen to get will follow a similar model: vanity/glamour options for GLA/PLD that are mechanically identical to any other sword.
