Disney and Lucasfilm have always had a great relationship. Not only did they create two awesome Star Wars rides (the original Star Tours and now Star Tours: The Adventure Continues), but also an Indiana Jones ride and and Indiana Jones stunt show in the theme parks.
Also, John Lassaster is a Disney exec. You have got to be insane if anybody in the world...the closest living person that we have to a Walt Disney in this day and age...that HE will not be involved in the new Star Wars project. The best storyteller of this generation. Star Wars.
MAKE IT HAPPEN, KATHLEEN KENNEDY!!!
