An interview on Fast Company discusses Portal 2 with Valve's Doug Lombardi, with a warning there are spoilers within. At the conclusion of the conversation, Doug reveals they expect to release DLC for the puzzle/platformer sequel this summer: "We will be announcing some DLC for it, so folks can keep a look out for more content coming this summer. We'll be putting more details out about that in a week or so. We'll support that with more videos or more comics." Thanks Joystiq via Piki Geek.
