i think that everything is going to be delayed a little bit
"The client download will now be available to closed beta testers when we announce further details regarding the upcoming stress test here on WorldofWarcraft.com. It will not be available early as we originally indicated in the email we sent yesterday. While our initial plan was to offer the stress test client for download to closed beta testers ahead of time, this is no longer possible due to the extensive maintenance being performed on our servers. We apologize for any confusion this has caused. Please enjoy your weekend! "

i dunno i think the earliest anything will come is the end of next week
