It’s not coming back. I’m not sure where that rumor got sourced from but that source wasn’t provided and I’m betting it’s not a source anyone should be paying attention to anyway, LOL.
Why would you need to UPSCALE a restoration from the OCN? That just… doesn’t make any sense. The only way that rumor takes any sort of hold is if the person making it up knows the audience they’re trying to share it with thinks about this stuff like it’s video games.
Lucasfilm isn’t going to artificially motion interpolate this to 120fps. Nobody wants it. Almost nobody can watch it like that. There’s no point.
