Fresh off the presses: Kathy Kennedy, on whether or not there are plans to alter George’s “final cut” of the films: https://www.youtube.com/watch?v=ie6Cr3m344k&feature=youtu.be

The writing’s on the wall. “I wouldn’t touch those. They will always be his films”.
The only way an OOT release will happen, is if George Lucas gives his approval. I doubt Lucasfilm would start restoring the OOT on their own accord, and as Pablo Hidalgo hinted, George Lucas is not all that interested.
At this point Mike Verta’s restoration is our best hope. Once his pitch has happened, I suspect a copy will be shared with Lucasfilm, who will have to decide what to do with it: bury it, or get Lucas’ approval for some kind if release.
Either way, as far as I can tell an OOT release seems highly unlikely this year.
