As the article shows, thirteen episodes of the written but never aired "season six" of The Clone Wars will debut on Netflix in about two weeks. You may notice that most Clone Wars seasons are 22-24 episodes long, so this is not a complete season. You'd probably be right. Writing is the first step, obviously, and production and post-production comes later. Meanwhile, while the producers were in the midst of making season six, business realities intruded, and Disney bought Star Wars and the rest of Lucasfilm. This made the Cartoon Network contract unworkable (or at least undesirable) so the show was canceled earlier than it otherwise might have been. We're lucky that they guys were able to finish up thirteen episodes, I think.
There's also apparently some lost Darth Maul espisodes that weren't as far along, and were therefore never animated and can't be seen, even though scripts exist. These will be adapted to a comic book by Dark Horse in a few months (given that Disney also owns Marvel Comics, it's surprising that that contract still lingers, but no doubt it won't forever...)
As a lifetime fan of the franchise, even during it's low points, I'm excited to see this. I've thoroughly enjoyed this show to date, and I'm excited to see the new Disney XD show Star Wars Rebels when it airs this fall. And I'm excited to read the "Son of Dathomir" arc, even though I've otherwise kinda sorta given up on Star Wars comics (and in many ways, comics in general.)
Maybe this will be the impetus I need to finally officially playtest my Star Wars Microlite ruleset, while I'm at it...
