Just to add to my recent post, I made a decision over new year to stop buying 4k discs on release and wait for them to be heavily discounted. I will make exceptions for favourite classic films but for most others which are upgrades, will wait. Certainly in the UK, values for second hand discs...
I hope we don't have to wait until 2024 for White Christmas. Given that this was the first film to be released in VistaVision, it would mean waiting even longer for other VistaVision titles.
