Up to now there is no season 6... No one will comment, and there is no mention of it on Cartoon Network, or any of the Disney owned channels for next years shows. An insider at Lucasfilm told a podcaster in an interview that "Now is the time to make a Rukus in support of TCW, its future is not certain..."
I'd be happy if it didn't return. Personally I thought the ending of season 5 was good, and I'm happy at their decisions regarding Ahsoka. But it made me realise something... TCW has made me hate Anakin, Obi-wan and the Jedi Council, the whole mythos and nostalgia I have about the Jedi is gone because of this show.
