Multiple sources are confirming that the Blizzard background downloader is now beginning to download patch data for the upcoming patch 4.3, Hour of Twilight. We have been hypothesizing a release date of the next and final Cataclysm content patch around the late November/early December mark. Having the background downloader active now means that a good portion of the content for the patch has been finalized and is loading into our games as we speak. Now it is up to Blizzard to tweak numbers and encounter design rather than add new objects, art, and so forth to the patch.

As we learn more about the patch and its release date, we will be sure to let you know.

Brace yourselves for what could be some of most exciting updates to the game recently with patch 4.3. Review the official patch notes, and then dig into what's ahead: new item storage options, cross-realm raiding, cosmetic armor skinning and your chance to battle the mighty Deathwing -- from astride his back!
