Valve Confirmed At Gamescom 2011

After their complete and utter absence from the E3 scene. Yes, Gamescom, that other games convention that takes place for the strange human beings across the sea that pay for things with Euros.

With Valve deciding to attend, one can only imagine what they might be displaying at the showfloor. DOTA 2? Left 4 Dead 3? Half-Li-, er Team Fortress 3?
