I had queues all the time on WOW (everyone's game they rave about) and pretty much every other MMO I have ever played, especially during the first few days or weeks. Also, all of them were subscription games.

It just means that there are a ton of people playing the game, which is good, and that they are trying to force people to balance servers a bit at launch.

For the record, I waited 3 hours to get in-game last night. It sucked, but oh well. It will get better.
