I just hope filmmakers actually do treat the Star Wars universe like this in the future. So far I've sensed a lot of hostility and coldness concerning the extended universe from them. Marvel is slightly different because even their comics had alternative universes in other comics. But I share your hope. This would really be the smartest way, financially speaking, to maximize the franchise for years to come. Unfortunately, the way the trilogies are set up don't allow for the same flexibility as comic brands do. There are three trilogies, 9 movies, and they all follow in sequence according to Lucas now.
