Blizzard has announced the initial roster of heroes that you will be able to play as, when the game launches. The heroes range from three of their major titles, but I imagine that they will keep on adding new heroes once the game launches.
- E.T.C. (Tauren from the WoW rockband "Level 90 Elite Tauren Chieftain" or "L90ETC")
- Sgt. Hammer
- Demon Hunter
- Witch Doctor
