Um ... probably not. But the folks over at Market Saw seem to believe that they've uncovered secret galactic plans to create a brand new big-screen Star Wars trilogy in 3D. However, they claim these films wouldn't be directed by George Lucas -- instead, he'd pass them off to other directors like Steven Spielberg or Francis Ford Coppola (who Market Saw claims their source mentioned directly as a potential candidate). Yeah, definitely let me know when Coppola decides to direct a Star Wars film so I can look out my window and watch all the pigs flying.
Almost immediately after this rumor hit, folks began to read between the lines. Market Saw, who've been the unofficial Avatar fansite for awhile now, continually mention in their piece that Avatar has to do well in theaters in order for this new Star Wars trilogy to happen since Lucas wants the films in 3D and needs more theaters to come equipped with 3D technology. As AICN points out, it seems like someone at Fox is spinning a marketing web by putting the thought in folks' heads that if they go see Avatar, they'll be helping to bring new Star Wars movies to life.
From MS: "How seriously should you consider these rumors? Well it is coming from a source that SHOULD KNOW. This source is absolutely connected. So odds are it is seriously being talked about at Lucasfilm. Right now. Will it happen? AVATAR will have to hit and hit big and then all the stars have to align properly - all I can do is pass on the info."
