Is Prepped still confirmed to air? Or was that canceled? And is Unnatural History still going to be an hour each episode?
As far as I know, Prepped is still on the way. As for Unnatural History, I think that I read somewhere that it is supposed to an hour long series. I know that the pilot will be 60 minutes at least.
Thankfully, Cartoon Network still has plenty of animated programs on the way, as I really couldn't care less about another series about a teenage boy in school.
