Update 21:05 CEST - The registrations for american realms are now open !!!
Registrations for WotLK Beta open
The registrations for the Wrath of the Lich King Beta are now available ! For the moment you can only reach the page on the European Account Management Page and the "Beta Opt-in" link that was on the american account page vanished today. That's probably temporary and we'll warn you as soon as it's available.
