We are nearing the time till Valve's presentation begins (2pm PST, 10pm GMT) and our colleague Smash is on location at the Los Angeles Conference Centre, reporting back his findings. You can follow him through twitter right here - http://twitpic.com/6h3rt[br] [br]Update 1: So far since arriving, smash has wandered into the 360 demo booth and found a playable Left 4 Dead 2 demo. Picture here.[br]Update 2: L4D2 playtest in valves room. not an expansion. pc and 360 nov 17. screen shots later at hl2.net. no ep3 at e3.[br]Disappointing news, no episode 3 at E3. So Episode 3 really is an ambitious project, there is still nothing to show for it!? I am surprised.
