though the rumor says 4 discs per movie for the 4K sets and 3 discs for the BD
Right, I seem to have unintentionally caused some confusion when I said “three discs.”
The assumption is that the three-disc blu-ray and the four-disc 4k will have the same three regular blu-rays and the 4k will simply also include the final version on an actual UHD disc.
I doubt they’ll bother including a dvd copy.
