Portal 2, DLC will be free

Portal 2 came out not too long ago, but Valve has already announced that they're releasing DLC (downloadable content) for the game. Now, it has been revealed that the DLC will be free - and they didn't specify a console, so I'm guessing that means it's free on PC, PS3 and 360.

I'm surprised, because Valve usually only gives it away for free on PC and has to charge on the 360 to cover costs of releasing on the platform; however, this time they have released a game on all three platforms, two of which have Steam - allowing for instant updates through their own systems and cross-platform play between PS3 and PC.
