At Star Wars Celebration, Dave Filoni announced Season 4 would be the last for the show and it would be comprised of only 15 episodes. What do you think of this?
It's certainly very sad but as Filoni pointed out, at least the show will receive an ending unlike The Clone Wars. Only 15 episodes actually appeals to me as this means we will hopefully get fewer 'filler' episodes and more gritty episodes relevant to and that expand about the Star Wars mythos.
Very sad news still!
