"Star Wars fans have been hoping for Disney/Lucasfilm to release the unaltered, original cut of the first Star Wars trilogy, and according to sources from Comicbook.com, that's what they're planning to do.
The site reports that Disney is planning to release the original cut of the Star Wars trilogy on Blu-Ray. The goal of the project that has reportedly been under way for a long time is to release A New Hope, Empire Strikes Back, and Return of Jedi in their complete and original form without the redone special edition SFX. The plan was to release the Trilogy on Blu-ray before Star Wars: The Force Awakens comes out on December 18. The sources reported that Disney doesn't have the exact date due to the challenges they encountered. We'll keep you updated as soon as we get details about its release."
