hmm, no game demos which actually doesn't surprise me. Valve just released Portal 2 and they're going to release DOTA 2 soon-ish (...actually I'm sorta surprised there's no demo for that but then again I don't know anything about that game or how far along they really are) so I don't expect them to have anything to demo. :V But that doesn't mean they can't announce stuff. C: Like maybe progress on HL3/ep 3? Or the confirmed Portal 2 DLC. I would like to know more about that. :V

tl;dr, I'm not surprised
