It's been an eventful conference for Valve this year. They skipped E3, but returned with a bang, launching a $1 million Dota 2 tournament and a suite of accessible e-sports spectator tools . Just before Gamescom started, they released the first information about Counter-Strike: Global Offensive as well. No Half Life 2: Episode 3 news, though. Perhaps more protesters can persuade Valve to reveal something.
