I guess we had heard rumblings of an ending, but I honestly thought we'd get at least one more season - probably airing on Disney XD. So much is just left hanging there, so I'm glad we'll hopefully get some sort of resolution whether it is via "bonus content", direct to DVD releases, online, or whatever. It still baffles me what a freefall it was for the Clone Wars. It was really the darling of both Hasbro and Cartoon Network (and Lucasfilm) at the beginning, and slowly all three (maybe partially because of Disney) have swept it silently under the rug.
I'm sad to see it coming to an end. It had a nice run for a cartoon, since so many these days (particularly actiony ones - non Spongebob types) are lucky to get past the syndication number and call it a day. That being said, I have become invested in characters like Ahsoka, Ventress, Rex, etc. (or even Maul, Cad Bane, etc.) and I want to know what becomes of them. Hopefully we'll get more details soon. It is probably a topic for another thread/forums, but I read in one of the articles about this today how it seems that almost all prequel era stuff is being pushed away, whether it is the PT 3D releases, the CW show, or even the whole 75% OT/25% PT lineup of the new Black Series 6" line. Interesting how that has changed.
