In an earlier panel about WoW lore and quest design Blizzard Creative Director, Chris Metzen, commented about how the blood elves are completely addicted to magic. This mana/drug addiction extends into both their abilities and some of their quests.

An encouraging sign we've seen is that the mobs we were fighting appear to be entirely new character models.

Finally, there are a few other elements coming down the pike for the next few patches. Weather is finally coming to Azeroth -- which should make a nice change from the perpetual sunshine that rules over the world now. Or perhaps not, as Dabiri promises "rain, snow, and sandstorms like nothing you've ever seen."

Overall, the Blood Elves are definitely the 'pretty' race for the horde. When you jump as a BE male, they start to spin (right shoulder forward) like an ice skater. My native trollish loathing of everything elves writhed in horror. Class options for warrior, rogue, priest, mage.

AQ will require a world event to open. Both sides, alliance and horde have to complete “stuff” to open the gates. Once they are opened, then they are forever opened, it’s a permanent server change. All level ranges will be involved, as there will be supply gather and processing quests for the lower levels, and stuff ranging the spectrum. One side and/or the other will have to gather the four parts to a scepter to open the gates. It will take the average server 3 weeks to open it. If nobody does stuff, eventually the gate will open on its own.

I will keep you updated as I find more information.
