I belive the reason the noven Crusible have been delayed is because of the movies
Story in this noven was to let the new generation take over with maybe death to the big 3 Luke, Leia,Han.
But i think alot of info and story hadd to be re written because they are making the new movies.My guess is
the novel will be change to a story were after what goes on in the novel nothing is changed and leaves things
open for the new star wars movies.
