Well according to the Wikipedia site for the Clone Wars series, at least 2 episodes are fully completed. It's expected to air in 2008 during the late spring/ early summer (I would expect May, since that's Star Wars month). On TheForce.Net podcast for last week, Steve Sansweet (Lucasfilm's fan relations dude) said that Lucasarts will announce two new games at Celebration 4. I wouldn't be surprised if the the much rumored Battlefront III is one of the two. I've heard in the past that LEGO works about a year in advance and the new contract with Lucasfilm from 2006 mentioned that they would "continue its construction toy rights to the entire Star Wars galaxy, including an all new Star Wars animated television series currently in development".
