Slashdot linked up news "from the source" concerning new developments in the Star Wars universe. Lucas has now confirmed both a full-length (30 minute) 3D animated series based on the much shorter Clone Wars series, as well as a live-action TV series. The live-action variety will be set between episodes III and IV, and apparently will not concentrate on the same characters as the movies.
Lucas has always been a better producer than director, so I'm actually optimistic about this stuff. We'll see!
