Star Wars fans - I have some exciting news! We have wrapped production on all of the remaining Star Wars: The Clone Wars episodes, and while that might be sad news in one way, it's good news in another. It means you will finally get to see them. When, exactly, is a detail I cannot yet share. I can confirm that in early 2014 you will be watching the final episodes of The Clone Wars, including one of Master Yoda's most challenging missions. So, get ready. We've got Clone Wars and Rebels coming at you in 2014. Animated Star Wars is alive and well. Trust in the Force my friends.
