Although confirmation as to the show's move to Disney XD has not yet been seen, it is confirmed that Season 6 of the Clone Wars will not air on Cartoon Network. CN recently released a list of returning shows for the next season that does not include any mention of The Clone Wars...

At the moment, it isn't confirmed whether this means the end of the show, or a move to another channel(more than likely Disney owned). I hope, if this is a move, that it will be to ABC rather than Disney XD. Due to the fact that Cartoon Network is considered a pre-teen/teen channel, but Disney XD is considered an elementary aged channel. However, ABC is more of a teenager/adult channel. The show already holds a reputation of being a 'kids' show; therefore, a move to ABC would be best for marketing.
Let me know what your thoughts on all of these things are! And, until next time, MTFBWY!
