What I'm wondering is: will the 3D animation be cartoonish style, or will they go the Final Fantasy route and try to do photorealistic humans? I hope it's the former.
I, too, hope they focus on others besides Obi and Ani, since their exploits are already well-documented.
We know that the creators of the upcoming series are reading the existing Clone Wars books, comics, and other materials. (This is a good sign, for the third season outright contradicted a number of books and comics. In terms of EU continuity it was a total trainwreck; there's really no nicer way to put it.)
