Star Wars: The Clone Wars will not return for a sixth season on Cartoon Network. However, unaired final episodes of the series have been completed by Lucasfilm Animation and will be released in early 2014 in a manner yet to be announced (Source: StarWars.com, Dave Filoni on Facebook). It will potentially consist of about ten episodes and a soundtrack release of Kevin Kiner's original score (Source: Full of Sith).
A future episode arc is composed of "An Old Friend", "The Rise of Clovis" and "Crisis at the Heart". It re-introduces Rush Clovis as Anakin's rival for Padme's affections and includes bounty hunter Embo. It is partially set on the planet Scipio, home of the Banking Clan (Source: Star Wars Insider 137). A clip from this arc was screened for fans at Star Wars Celebration VI. Airing the Young Jedi story arc on Cartoon Network pushed the Clovis arc out of Season 5. Because it did not air as a part of the show's run on Cartoon Network, it will appear alongside the other story arcs being made available as "bonus content" (Source: RebelForce Radio). The arc is written by Christian Taylor (Source: Brent Friedman on Twitter).
Another upcoming story arc investigates programming within Clone Troopers as a potential mechanism behind Order 66. It features Anakin Skywalker and his 501st Legion along with the returning character of Admiral Trench who was last seen in "Cat and Mouse". A clip from the arc can be found at YouTube. The entire arc will be made available to fans as "bonus content" (Source: StarWars.com). The arc is written by Katie Lucas (Source: Brent Friedman on Twitter).
The "bonus content" will include a story arc written by Christian Taylor in which Plo Koon and the Wolf Pack attempt to unravel the mystery behind disappearing Jedi Master Sifo-Dyas (Source: Brent Friedman on Twitter). A clip from this arc was unveiled by USA Today. The same arc prominently features Yoda and more closely examines the concept of Force ghosts as seen in "Overlords", "Ghosts of Mortis", The Empire Strikes Back and Return of the Jedi (Sources: Matt Michnovetz on Twitter, Bombad Radio). An additional clip from the arc in which Yoda escapes from a Jedi medical center was shown to fans at Star Wars Weekends in Orlando. Dave Filoni posted concept artwork for the arc on his Facebook page.
