A lot of people are unsure as to when Valve intended to send an RC to Vivendi. Some people are under the impression that Valve were going to send off the first RC when Half-Life 2 went bug free. I don't think that's the case. Here are a few quotes relating to the RC and the state of Half-Life 2. This quote is really old. From the 18th of June, no less. It's mainly included here for completeness. This quote is the first mention of a Release Canditate. It shows that Valve were intending a 30th of July RC. And also explains what an RC canditate is. Now, this contradicts the quote above. This quote clearly states that they aren't going to send a Release Canditate till after the CS:S beta has started (or ended). This makes more sense if you consider that there's no point in submitting an RC until you think you have a bug free game. This is an important quote because people seem to ignore it and concentrate on the one quote above. Valve changed their plans, they decided to submit the RC after the CS:S beta started. They are allowed to do that. This is the date that the CS:S beta was meant to be preloaded. It doesn't mean much unless you compare it to the quote below. Now, this quote was from the 20th of July. 16 days before the 5th of August. Which is a bit of a coincidence. I think it shows that Valve were intending to start the CS:S beta when they thought that Half-Life 2 was in a bug free state. This would ensure that the bugs that are found would be new bugs, instead of bugs that they knew of. It also explained why the CS:S beta was delayed by a few days. They hadn't finished fixing all the bugs, and some of them could've been important bugs that would've meant the game wouldn't run on some graphics cards. This just confirms what the third quote said, that . The CS:S beta still has Source related bugs in it. I wouldn't be surprised if the CS:S beta ends around the 15th. This would be about a month since it started. The word "by" implies that the RC could be send off earlier, depending on how they sort out the CS:S beta bugs. There don't seem to be that many CS:S beta bugs that need to be fixed. It seems very stable. Which is good. I hope that cleared up any confusion that anyone had. It's in my view that Half-Life 2 was in an apparent bug free state when the CS:S beta began, and Valve are just waiting for the CS:S beta to enter a mostly bug free state. Then they'll send off the Release Canditate.
