My friend just pointed this out to me. L4D 2 is supposed to come out November 17 this year. Here is the teaser. Link What I can tell from the teaser: The game takes place in New Orleans, Louisiana. New melee weapons are appearing, such as the chainsaw (w00t), a fire axe, a baseball bat.....and apparently a frying pan. The Tank is still involved, with possible new types of zombies. The pistols look indifferent. Unsure about other weapons.
