Unless George Lucas dies in twelve years and the Lucasfilm board of directors decides to restore the most lucrative and popular title in their entire library. Yeah, that would never happen.

The entire debate about "never" seeing the OOT again is a bit moot. The OT will be public domain at some point. Some of us might even live long enough to see that day. But more than likely, the films will be released not long after Lucas dies. Or before: remember, Lucas has been softening on the issue gradually, especially as his friends and colleagues have begun publically questioning him. In 1997, he spoke about the OOT being destroyed and forgetten because everyone would be watching the SE. In 2004, he instead framed it in terms of it being unfortunate that people preferred the version he doesn't like. In 2006, he then released the OOT, stating that he'll see if people really want it after all. In 2010, he said that the "classic version" the trilogy will be put on the backburner until the SE is done because of cost.

So never say never.

Plus, on a long enough timeline, someone will do their own 35mm scan. Maybe not this year or this decade, but it's simply inevitable the longer this all goes on for.

So rather I would say it is the opposite: Lucas is the one fighting a losing battle. When he is dead, everyone in his company will be doing their best to get the films released. And even if they don't--the films will be public domain, and all those archived prints in the Lucasfilm vaults and Library of Congress and Fox studios will be put to good use. You see, that's the beauty of this all: Lucas can't take the films with him. They belong to the public at the end of the day. For all his efforts, all his wishes and all his actions, he will never win the war, even if he's won a few strategic victories right now. He's already lost the war, we just have to wait around for it to happen.
