This in from Blizzard, the next patch is immanent as soon as the servers are back online.
New Patch Notes Available!
Despite the fact that the US World of Warcraft beta test will remain offline as discussed above, the new patch has been tested and finalized, and we are looking into the possibility of making it available for download sometime this weekend. Should we be able to do this, the beta test will still remain offline, but players will at least be able to patch up and be ready to go for when the servers eventually come back online.
The patch notes have also been finalized and are ready for viewing. You can find them
here. Please note that while we put every effort into making the beta patch notes as complete as possible, some changes are bound to go undocumented. This is because there are an extensive number of changes that are being done in every area of World of Warcraft up until the moment the patch content is locked down, and our primary focus is on completing the game for launch. After launch, patch changes will be documented more completely.
