With speculation overwhelmingly pointing towards an upcoming Team Fortress 2 animated TV series, the official website for US TV Network Comedy Central's Adult Swim department.
A promotional page
on the Adult Swim site describes the venture only as "something you'll probably enjoy", teasing interested visitors with a message "To learn how their video game peanut butter will be getting in our network's chocolate, come back next week," and directing them to a newsletter sign-up page
that features an image of TF2's pyro character with the caption "We're your new family now".
Adult Swim is known for its adult-orientated animated TV series such as Aqua Teen Hunger Force, Venture Bros and Sealab 2021.
