The bad news: as is customary with Valve, the DLC is scarce on details; apparently they like teasing us. The DLC is currently in development and 'targeted for release early next year' (adjust accordingly for 'Valve Time'). Also, they never really specified if this new DLC would make it to both PC/Mac and consoles, although indications are that this will be arriving on Xbox 360. We just don't know for sure, and likely won't for many months. Look for [possible] new Portal 2 DLC early sometime next year.
