WoW and the Burning Crusade Expansion

The folks at Blizzard have an expansion pack coming out for World of Warcraft, called Burning Crusade. You can watch the trailer, which combines their concept art and final rendered images to form a really cool narrative. They've brought back the blood elves, and the timelines are a bit confusing now but it still looks awesome.
There are 2 new races, flying mounts, and a new profession of jewelcrafting. A big one is that they've raised the level cap from 60 to 70. BUT... before I can even THINK about grinding in Azeroth, I need to return to my own grind to "DING" academically.
