World of Warcraft Expansion News

I was waiting for more news on it before posting, so I imagine some of you are already aware of the screenshots and news of the first World of Warcraft expansion out there in the wild. Voodoo Extreme has the highlights, and Joystiq is carrying some beautiful screenshots. So far the three features that have my eyebrows raised are: Blood Elves as a new playable Horde race, a high level Flying Mount for the Outlands, and (most exciting) cross-server Battlegrounds. This last would be a huge boon for the currently questionable organized PvP play, and I really hope they swing it.
