Also I don't think we will have 10 allied races this time, maybe even it will be 0. Who knows, maybe they have prepared some stuff for patch content already.
About 9.3, I think Sylvanas raid will be in Maw, we will free a lot souls there (tier 2 is usually when we accomplish major goal from launch). Expanded Maw would be some kind of 'deeper Hell' with Jailer citadel.
They could always use some twist and make Arbiter big bad, but I don't think it will be the case. Imo they want SL to be "classic" expansion with clear villain, focused on its theme like Wrath or Cata.
