This set has me a little bemused. Selling this as a 4k set is misleading. None of the 9 films are available in anything higher than 2K resolution. Unless Disney have gone back and rescanned original film prints of either the original release of the OT or the Special Editions, these will be based of the the previous digital versions available on blu-ray, so not 4K. The prequels were shot digitally at 1080 and 2K, so there were never any film prints available to rescan at higher resolutions. Then even the new trilogy was created at 2K (unless they renedered all the CG at 4K, which I highly doubt given that VFX houses don't do tgat due to time and cost restrictions).
So at best, all these are are upscales of all the previous releases. If you want the OT in 4K, go get it for free at 4K77, 4K80 and 4K83 (or donate a little for the hard work by the guys who created it). Get the PT on the already existing and far cheaper blu-rays and do the same with the ST.
Ok, so there's a **** tonne of extras, apparently. But reportedly no deleted scenes. I'm guessing a bunch of previously released making of documentaries?
Bit of a con if you ask me. This holds zero interest for me, especially at that price.
