Valve has revealed the next batch of downloadable content coming to Left 4 Dead 2. There's something old—maps from the original Left 4 Dead—and something new—a campaign called "Cold Stream"—coming for owners of Left 4 Dead 2.
The official Left 4 Dead blog writes that the three remaining campaigns from the first game, Blood Harvest, Dead Air and Death Toll, will be released as part of a map pack for Left 4 Dead 2. Presumably, that will come with balance changes, bug fixes and whatever else it takes to make those levels mesh with Left 4 Dead 2's style of gameplay.
Additionally, the community-made campaign "Cold Stream" will also come to the PC, Xbox 360 and Mac. Expect it to be story-free, which Valve says makes it possible to deliver these things faster.
No date, no pricing announced yet. But if you're looking for a little more detail, read on.

Having all the L4D maps (outside of Crash Course) on L4D2 is just awesome. I can't wait. Plus Cold Stream should be good.
Odds are it'll be free for the PC (since I'm pretty sure you can get all these maps already, just not as mods) and the typical 560 MS Points/$7 for the Xbox 360 version.
