See you in Pandaria!
[edit] Due to the large number of invites sent there are some that bounced back for various reasons, and we'll be working to apply those invites over the next few days. If you haven't received your invite yet it's likely you're one of the few affected by such an issue, and rest assured we're working to get you into the beta as soon as possible. Please be aware that customer service does not have the ability to flag accounts for beta. Thank you for your patience.
