For those of you anxiously awaiting the new 1.3 patch for Counter-Strike (that adds the much-touted integrated voice communications), it looks like your wait has been extended a couple weeks according to couter-strike.net:
As you can tell, the anticipated "first week" of September has come and gone. Things change quickly with large releases like this, so I can only give my best estimate. Now it"s looking like in the next 2 weeks (hopefully next week, but that could change). There are a lot of factors, such as Retail and Mod version issues lining up with Half-Life patches to support the new Valve technology.
