If it's true, 2017 is looking up already! As a possibly 40th Anniversary present, check out this article: "4K Theatrical Restoration of the True Original “Star Wars” possible for 2017." A choice quote:
"According to recent comments made by Rogue One director Gareth Edwards, a 4K restoration of Star Wars Episode IV “A New Hope” does indeed exist and now the only real question is whether or not the cleaned up and sharpened version of the movie will be hitting the big screen once again."
I have no idea if it's true, nor which version to which they may be referring, but it's certainly interesting and may mean yet another revision is coming - or even the first version from 1977. Hey, I can hope!
