According to starwars.com, a new untitled animated Star Wars series is in the works. The website sheds a small amount of info on the upcoming show, mentioning that the creative minds behind both Robot Chicken, and The Daily Show will be the creators of the series.
The website goes on to explain that the show will be a light comedy, however with Robot Chicken's creators, Seth Green and Mathew Seinrech behind the wheel of the new show, I can only assume that the age group that Lucasfilm will be targeting will be more of an adult audience, compared to it's current series, The Clone Wars which is aimed largely at children.
I really have no problem with this however, as long as the show doesn't step on any toes or delays the upcoming Live-Action show.
We'll have to wait and see how the show develops.
