Well, that was mighty sarcastic.
Next time, instead of adding insult to injury, just type a logical response, the both of you...I wouldn't be surprised if a demo is released, in order to highlight any new developments in the game engine, however, I believe Frictional Games will just release the second episode, with no demo - not only is it just easier, I think that they expect majority of their support will come from people who have already tried the first episode, and/or the tech demo.
That's my take.
