The queue was very high because Blizzard was letting everyone line up to get their characters copied, and not actually doing any of the copying yet. However now that they're copying the actual characters over to the PTR, the queue is diminishing fast.
You can get in line to copy your character over via the "PTR Character Copy" link on your account management page. Please note however, that at this time Blizzard is not allowing any more characters to be queued for copying, but that can change at any minute.
This is a good indication that the PTR will be up very soon. We're fully staffed here at WoW Insider HQ and will be bringing you the latest as soon as the PTR goes up. Hopefully including some juicy patch notes, screenshots and detailed information on Ulduar, and our first glimpse at how exactly dual specs will work.
