Looks like the live action tv series will remain a lost chapter in the history of the star wars saga.
With the sale to Disney, Lucas transformation of Lucasfilm from theatrical films to arena of live action television now won't happen.
The tv series was going to have Vader in in it and Ronald Moore who revived Galatica worked on it.
Not really one to resurrect threads but Disney returning Lucasfilm to primary a film entity when Lucas wanted to move to tv is interesting. With Lucas in charge we would have gotten more prequel material and no sequels set after Jedi.
