I have noticed that when you do the introductory quest in the Ashen Battlefield you get to fight alongside various NPCS that are pretty much templates of some of the classes we can use, judging their attack animations as well.
Knox - Great Weapon Fighter
Xuna - Trickster Rogue
Celeste - Devoted Cleric
Then there's Makos, the tiefling. I thought he was a Control Wizard, but then I saw the quest log indicating him as a "warlock" and when I saw him fighting, he was wielding a dagger and throwing bolts of dark energy with it. His animations were nothing like the Control Wizard either.
I may be reading too much into this, but could this be a hint that the next released class will be the Warlock? (presumably the Scourge Warlock)
