Valve announced the Cold Stream downloadable content for Left 4 Dead 2. While PC and Mac users can finally get their hands on the DLC, there is no date of arrival set for the Xbox 360 version, yet. All that has been reported is that the DLC will hit Xbox Live Marketplace at a later date and of course, it will not be free like the PC version, but that seems to go without saying.
Responding on their Twitter page:
We are working with MS on a release schedule. We don't have an ETA yet but we hope to have it out soon. It will be 560pts.
Plus 4J Studios teased some skins through a tweet that read:
Some skins from the coming Skin Pack 2 might be shown as part of an announcement from another games company on the 24th. Watch the web 
Valve also announced that Minecraft: Xbox 360 Edition users will be getting all eight Left 4 Dead survivors from both L4D and L4D2 sometime in August. Now to find out what other skins will be included in Skin Pack 2.
