User blog comment:Commdor/Rumor: ME3 "Rebellion" Multiplayer DLC Incoming/@comment-3228423-20120502174547

No info on new enemies? Hmm, shame, cause that'd make multiplayer a bit more diverse. Then again, they probably won't expand the enemy factions beyond single player.

Would definitely love to see what these Phoenix classes are, but somehow, I agree that they're most likely prothean given the DLC From Ashes gave us.
