In a cryptic teaser page, Adult Swim has revealed that the company behind great cartoons like Venture Bros, The Brak Show, and Space Ghost: Coast to Coast (and horrible live-action bull shit like Tim and Eric) will be collaborating with Valve in some capacity.
The teaser page includes Twitter hashtags for Adult Swim and Team Fortress 2, but little else is said except that the reveal will happen next week.
My guess? Hats... endless amounts of hats for TF2. What's your guess?
