Bravest Warriors is about to be a series. Fredearotors been showing off production sketeches on their blog. If you haven't seen the pilot, it's about 4 space warriors who go through space fighting evil. It still has Pen's sense of humor, but I still like AT more. The other mystery is if it's airing on Nickeledeon or not, there's no place where it says it for Cartoon Network, but I think it be too hard for Pen working on two seperate show for two different networks.
Here's some early work on the show, it seems Phil Rynda from AT is now working on it. Also the characters have gobne over a major overhaul.
