I fully expect the original three films to be available on Blu-ray by the end of next year. FOX isn't going to refuse to distribute them.
My real hope is that Disney and Lucasfilm quietly place all the "Episode" movies into a separate Star Wars canon... like this:
CANON A
Star Wars
Star Wars: The Empire Strikes Back
Star Wars: Return of the Jedi
Star Wars: The Force Awakens
CANON B (The George Lucas Canon)
Star Wars Episode I: The Phantom Menace
Star Wars Episode II: Attack of the Clones
Star Wars Episode III: Revenge of the Sith
Star Wars Episode IV: A New Hope (Special Edition)
Star Wars Episode V: The Empire Strikes Back (Special Edition)
Star Wars Episode VI: Return of the Jedi (Special Edition)
