A Q&A with LucasArts President Jim Ward on Yahoo! News (thanks Frans and Voodoo Extreme) reveals plans for a previously unannounced Star Wars RTS game in the works at Petroglyph, a developer comprised of ex-Westwood employees:

As a result, we will have new live-action and animated TV shows over the next few years, and I think there's a bright future there for games based on these new properties as well as original "Star Wars" games like a new real-time strategy PC game that Petroglyph is developing for next year. This game will take the (real-time strategy) genre in a new direction and will balance gameplay between the hard-core gamers who buy these games and the broader audience that's familiar with the "Star Wars" brand.
