Either those bonus discs are going to be a real waste of storage space, or we’re getting a considerable amount of bonus content for the OT and PT that wasn’t on the complete Bluray set, which had just three bonus discs for the six films. The ST stuff will just be the same stuff that came with their recent Bluray releases, I imagine.
kinda mad the standalone 4k release for rise of skywalker doesn’t appear to include a blu-ray bonus disc like the last few films have.
