Valve games never have "cut scenes" at least in the sense that you lose control of your character and have to watch a bad movie. If you watch the developer's notes titles in most games the challenge they have is getting players to look in a certain direction for things other games would cut to a cut scene for.
I imagine Left4Dead will do the same thing.
