Clone Wars has received an order for twelve new episodes, which means there’s time for two or three arcs.
Wouldn’t it make sense for the Siege of Mandalore to be one of those arcs?
Now, Dave Filoni did not confirm at the Comic-Con panel celebrating The Clone Wars’ tenth anniversary that the revival would tackle the Siege of Mandalore, but we do know that the new episodes of the series will continue arcs introduced in the show during its original run.
As fans will remember, the show was fast-approaching the timeline of Revenge of the Sith, so there were a number of loose ends that needed tying off for the show to be truly satisfying.
