I wasn't even aware there was a 6th season of this popular show. I've been eagerly anticipating the new Star Wars Rebels that will air later this year. I went to IGN.com to look up something else completely different. And then I saw it. An article giving a review of the 6th season. And per the information I read, its been on Netflix since the beginning of February, a total of 13 episodes that just concluded yesterday March 7th. And as of March 7th, ALL seasons, all episodes of The Clone Wars are now viewable on Netflix. All I can say is, I hope the 6th season will eventually come out on DVD so that I can add them to my collection.
Special note - the last 4 episodes will focus completely on everyone's favorite little green Jedi.
