When George Lucas sold his company to Disney, it wasn’t just for three more Star Wars films. There’s plans for a number of spin-off stories, including possible stand alone movies with Han Solo, Boba Fett, and Yoda.
It’s been a bizarre time of ups and downs in the Empire. The franchise is of course starting up again with JJ Abrams at the helm, but at the same time Lucas Arts shut down, bringing an end to the (current round of) Star Wars video games, while the Clone Wars animated series was also cancelled.
Even if George Lucas swears there won't be any more Star Wars flicks and he's retired, the franchise will continue to storm on for quite some time.
