I don’t know if someone has mentioned this previously (my apologies if it has), but if LFL released the OT Special Edition it won’t likely be a true 4k format. The CGI effects were no doubt rendered at 2K, so even if you upscale them to 4K - the quality of the video will be equal to that of 2K (half of the prequels were shot at 2K) and you could end up with a 4K/2K hybrid. It shouldn’t be impossible to overcome this - but it certainly wouldn’t be a simple process. From a financial point of view it would make practical sense to do the Theatrical Editions of of the OT - even there, I expect it’d be still be somewhat an involved process. It really comes down to how far they’re willing to go and for what price.
