As it turns out, the Lost Missions weren't the last episodes for TCW. As a sort of special treat the day before the premiere of Rebels, Lucasfilm has released four brand new, completed (sort of) episodes, the arc of which is called Crystal Crisis on Utapau. This fully scored and voiced pre-visualization of all four episodes of the arc focuses around a giant kaiburr crystal that was being sold to the Separatists. It could absorb and amplify any energy source into massive beams that destroyed absolutely anything it touched. My guess, Dooku wanted to jump the gun on building the Deathstar with it, as Yoda mentions many ancient Sith super-weapons were built around similar such large kaiburr crystals. While the animation is strictly pre-viz, it has some really great moments between Obi and Anakin, who now sports his ROTS haircut. They also discuss the touchy topic of Ahsoka leaving the Jedi in season 5. Would really love to see the episode finished and added to the Lost Missions/Season 6 DVD whenever it (finally and please ;D) launches. The episodes have been publicly uploaded to the Star Wars main webpage under the heading Clone Wars Legacy, along with news of a Ventress/Vos arc called The Dark Desciple to be released as a novelization, and wrap-up of the Son of Dathomir comic mini-series by Dark Horse.
