Below is a statement issued by Lucasfilm Animation:

“As we enter into an exciting new era focused on the next Star Wars trilogy, Lucasfilm has decided to pursue a new direction in animated programming. We are exploring a whole new Star Wars series set in a time period previously untouched in Star Wars films or television programming. You can expect more details in the months to come.

As part of this shift, we have also made some key decisions affecting Star Wars: The Clone Wars and Star Wars Detours.
