With current animating programs it surely wouldn't be anything challenging. The only extra work would be on refining the details and doing the lighting
Yea, but I think I would appreciate it more if they attempted it hand drawn rather than using a program saying that they are doing very well on the Clone Wars animations in 3D! But wouldn't it be cool to see traditionally drawn stuff similar to what they produce in Ghibli (no the Ghibli style, just the detail of animation!).
