Left 4 Dead Expansion Lets You Choose...

...who lives and who dies, apparently. As it stands Bill dies in The Passing, and there's going to be comic that explains how and why that happens. But it turns out that in The Sacrifice, you can - in keeping with the game's own moment-to-moment decision-making - choose who dies for yourselves. This comes via Kotaku, who point out that in this GameTrailers' chat with Valve, Mr Faliszek reveals that this next bit of free DLC for Left 4 Dead (and also Left 4 Dead 2, it'll work with either) enables us to experience what happened in the events of The Passing from the perspective of the original cast. The events of this new expansion will, therefore, allow you to choose which of that original cast winds up dead. The Sacrifice also gives Left 4 Dead 2 owners a version of No Mercy, which seems like a splendid little bonus.
