I’ll probably buy the first Episode I-IX Complete Saga 4K + standard Blu-Ray set and ditch all my old discs after that, whether the OOT is included or not, if I’m honest with myself. Just to have everything in a nice matching set and be covered for all future fan projects, and the ST in 4K. But that would be my last OT purchase unless a restored OOT is released, and would definitely be my last PT purchase unless I’m forced to rebuy themb for an official restored OOT.
Oddly, I don’t think I’d buy said set if it included Rogue One and Solo. I’d rather have just the “Skywalker Saga” itself in a boxed set and have the standalone movies all separate.
