Here's a fun Pixar style Star Wars poster that was created by Phil Postma. This is the same guy that brought us those great sets of Superhero Pixar art and Star Trek Pixar art.
It would be fun to see Pixar take on an animated style Star Wars film. I could easily see something like that happening. If not Pixar, I'm sure Disney Animation will eventually do something. I'm sure it's one of the many things they've talked about.
