Back in February, Valve teased that the company was working on a major new Team Fortress 2 project. With the announcement that the developer is working with Cartoon Network on a project, it could be that Team Fortress 2 will be a new Adult Swim show.
According to a promotion on Adult Swim, "Adult Swim & Valve are teaming up for something that you'll probably enjoy. To learn how their video game peanut butter will be getting in our network's chocolate, come back next week."
It'll be interesting to see how a show starring The Heavy and Sasha, along with the Scout and the Spy and the rest of the game might gel.
