I just can’t see the OOT ever getting released on its own. As a 2nd disc feature, maybe.
I’d buy a set with both SE and OUT cuts without hesitation. It’s the prequels that would aggravate me. But Lucasfilm has never forced the prequels on people who don’t want them. They have OT sets and have released individual titles as well.
The mere fact of the huge SW pirate market should be motivation enough for them not to force OUT buyers to pay for the prequels.
