Cataclysm is closer than we imagined according to the live of patch 4.0.1 PTR noting, whose Classes changes are up with new talent builds and new glyphs, but Revamped old zones, new graphics, archaeology, guild leveling, flying in Azeroth and new content are not available.

According to a reliable information from mmowned, which is a well-known unofficial site for world of warcraft source, the Cataclysm will released on November 18, 2010. Although it is not given by Blizzard ever, we also have good reason to believe that the release of Cataclysm is coming undoubtly.

Patch 3.9 will launch all of the new 1-60 content, the new class/race combos (except Goblin and Worgen), and a host of pre-events that will culminate in Deathwing's emergence. Blizzard is still trying to decide whether Archaeology will come out before or when World of Warcraft: Cataclysm releases.

The latest PTR client is labeled 4.0.0.12824, and is a whopping 16GB of information. While the PTR servers are not live, you can still download the latest version of the PTR client by visiting the official website.

We dare say that patch 4.0.1 is the last patch before Cataclysm release, so it does not contain any changes of the Old World and the content belongs to Cataclysm except the feature. However, patch 4.0.1 possessed some unique changes include setting up some systems, profession and interface as well.
