There were concept drawings when the game was announced. If I have my facts straight, there was
- a warrior or warrior-like character on horseback
- a female in a white cloak with a double-bladed pollarm
- a weaponless man (thought at this time to be a brawler)
As much as I would love a brawler, it doesn't make sense for them to make 2-3 melee classes, so I personally think the last one may be a new kind of spell caster.
