So what about that free DLC that we were supposed to get for Portal 2 this summer? Well, the DLC is still free, but it won't be out this summer - unless you count September as summer. I don't usually, but since this is Valve we're talking about I will be willing to make an exception. This time.
Kotaku asked Valve's Doug Lombardi about it and it looks like the free DLC is still on track, coming this September. It will be available for all the formats the game was released for, but no word on what it will actually include yet.
