* Garrosh is confirmed to be the new leader of the Horde. He has redesigned Orgrimmar and the Taurens and Orcs are the only races allowed in the center of the city because they're the only ones strong enough to defend it.
* The Ruins of Lordaeron / Undercity will be expanded with a pit opening into the Undercity.
* Zoram'gar Outpost in Ashenvale will be changed to a Warsong Hold style base.
* Stranglethorn will be the most altered zone.
* Apparently Southshore wasn't retaken by the horde (it was mentioned during Blizzcon) but has succumbed to tidal waves.
* The new raids will be more like Naxxramas than Sartharion. (Probably means that we won't get one-room / one-boss raids this time)
* There are a few extra details on the lore behind the Goblins and Worgens starting zones, just check WoW.com's Article for that.
