I found something interesting in a post over at the avsforum. This person's dad apparently sat next to John Lowry on a plane flight. Here's the relevant text:

"He also mentioned that they're working with the Star Wars movies again, and have gone back to the originals for the groundwork. This is probably for the 3d versions (I would assume the masters for use with the Blu-Ray set are finished already). He implied that this restoration means they will have restored versions of the theatrical Star Wars movies, but that they have had no indication from Lucas that the movies are in the pipeline for release in their theatrical versions."

Here's the direct link to the post:
