My guess is if anything is happening, that they’re scratching their heads on what to do. They’ve spent decades releasing the OT together - now it’s the 40th anniversary of SW, but they only have one restoration ready. I can imagine the argument whether to try and rush the other two restorations, or release the original theatrical versions “from the vault” for a limited time on each of their 40th anniversaries, culminating in a 4k Trilogy rerelease at the same time Jedi is released on blu.
