Didn’t the Special Edition restoration take 2 years to do? These things do take time.
Yes, though it doesn’t take 5 years to restore 3 movies, especially not for a company with the resources of Disney.
From what’s leaked, apparently the scans at least started in 2022, though I’m not sure if all scans were done then.
There was apparently an original 6K Cintel scan. Then they went back at some point later and did Cinelab 6K scans and 8K scans of the VistaVision.
Not sure if those were also done in 2022, or later.
But all of the leaked clips have a 2025 copyright date on them, so I’m not sure what work was done between 2022-2025.
Again, a person with your limited information should not be answering questions like this. The cintel scans were done in 2012 or maybe a bit later (around 2015-ish), then the cinelabs were done very recently (perhaps even last year…), then there was a photochemical restoration, then it was scanned in at 8K, and no, not just of the vitavision…
