Today, we invited people who had pre-ordered up to the very beginning of October (roughly). Tomorrow, we're going to be inviting the same number of people again; that will take us up to the last week or so of November. On Friday, we'll be inviting even more, and we'll give you an update on that tomorrow.That's good news for those who pre-ordered late and who otherwise might have thought they'd have a much longer wait.
You'll see more servers coming online tomorrow, and almost certainly there will be some queuing. That was always expected. As a reminder, our plan here is to maintain healthy server populations post launch, and during the excitement of launch that will mean queues. That said, we'll be working hard to keep those queues reasonable.
