I think this is a tough call. I can see it both ways but I have a tendency to think they will not. We don't know any of the details of the Disney deal, but I have a feeling there was a part of the deal where George Lucas explicitly stated that the only versions that could ever be released would be the Blu-ray versions. He probably kept the original negatives as well, if they even exist.

The SE's are his vision and version of Star Wars and I don't think he would want anyone undermining him. He spent a lot of time on the SE's and he has gone on record that that is the way he always wanted them. Given how stubborn he is with his property, I tend to think this was included in the Disney deal. I may be wrong, I hope I am, but I'd bet we won't ever see them.

Mind you, I absolutely would LOVE a Theatrical Blu-ray and I'd be the first to buy them, but my gut tells me it won't happen. We can only hope...
