It appears that Valve, the creators of the extremely popular and well selling Portal 2 is currently working on a new piece of DLC for the title. The DLC is set for release sometime early next year and will contain a huge update that will ensure that people never grow bored of the title.
The DLC will add in a major update that adds in a supposedly easy to use in-game map editor that will let players design and build their own single player and co-op test chambers to share with the community who can then rate and vote for their favorite ones. Unfortunately Valve did not announce how the editing would work exactly nor did they say if we can expect to see this DLC arriving on any other platforms besides the PC and Mac.
