"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. Regardless, we really think you guys are going to like the voice communication and proxy spectator mode -- both new features will add great depth to all Half-Life mods. We've tested the voice comm even on the slowest connections; everybody will be able to enjoy it. Keep an eye on cs.net -- things are about to get crazy. "
