I hope that they do! That would be great if Disney would do that, considering that a lot of the Star Wars prints, (such as the lost 70mm print of The Empire Strikes Back, the IMAX print of Attack of the Clones, and the 1997 version of the Special Edition) have not been publicly released on any home media. But we all know that George Lucas will not let Disney release the original versions, so my guess it that it is unlikely that they will.
in what way is ESB 70mm “lost”
