On the latest episode of Gametrailer TV Chet Faliszek explains to Geoff Kheighly how there will be only three of the original survivors to appear in the new DLC. There will be new, future DLC for the original Left 4 Dead that leads up to the events in "The Passing" that will force one of the survivors to make the ultimate sacrifice for his team.

Why do the L4D1 guys have to die, they were the best characters...

Rochelle should be the one getting killed, that way nothing of value will be lost.

Also, see Aerowyn? They're following through with their promise!
