The next character will be.... Black. In skin color, maybe soul, but who knows. Basically thats the only thing that was present in the previous Diablos that is not currently present (AFAIK) IN DIII is a black character. They may go on a limb and do something crazy like add a nonhuman player character, but i think that's unlikely seeing as how they recycled the barbarian and necromancer (witch doctor). As for class it will be something ranged, a ranger perhaps. hopefully it will be something new and unique, i just hope to god it's not a rogue.
