I think we might get a companion based on all the standard player classes, each of varying morality/ethics, not to mention we the player character can choose how good/evil we want to be. The BG series was great for having a party that complemented your morality to ensure cohesion and cooperation between the group. So far we have a Wizard, Warlock, Cleric, Warrior and Rogue class companions, that leaves plenty of room for the other classes.
