Valve has announced the next DLC that the team is working on for Portal 2. They are currently working on an in-game map editor that will allow players to create their own single player and co-op test chambers. Players will also be able to share their maps with the rest of the Portal 2 community in a fashion similar to LittleBigPlanet complete with a peer review/rating system.

While the Source Developers Kit has technically allowed such things already, the in-game editor will make the whole process easier for the layman.

Valve is looking at a release date in early 2012; however, we all know what can happen to Valve’ release dates so we’ll have to see what the reality is next year.
