Is Blizzard prepared?

The tagline for The Burning Crusade is "You Are Not Prepared." Based on what I saw tonight, Blizzard is not prepared for the expansion either. It took me awhile to grab a good screenshot, I started out at 583 in queue, 57 minutes. Post after post on the General forums complaining about long queue times. With the number of people coming back to the game for the expansion pack, what kind of queue times and problems can we expect? Oh well, it gave me time to get a few new raids scheduled. Hopefully people can get logged in when I want to start.
