How long will consumer demand allow for three competing formats?

[Gbpxl]

As of this typing, there are three formats that movies are still produced on; DVD, BD, and UHD BD. None of these formats show any sign of dying off any time soon. However... I only see two of these formats really surviving ten years from now- DVD and 4K. DVD still has a place for lower-income consumers and/or people who dont have fast ethernet to be able to stream. The enthusiasts have mostly jumped to 4K. Where does that leave BD? If a film collector has high speed internet and is still going out of their way to buy physical media, I believe most of them would prefer to spend the extra $5 on the 4K version. Especially when 4K TVs have gotten so cheap in the last couple years.

Now personally I havent made the transition to 4K yet, due to my TV not being able to handle HDR and the bitrate. But once it craps out on me I will be buying a 4K TV and subsequently I will no longer buy 2K discs, but 4K instead

Criterion has yet to release anything on 4K yet and I dont understand why. so there certainly are some collectors like myself holding out for now but I think that market will continually shrink until there isnt enough demand for the "in-between" format for them to justify mass producing them. so I am guessing that by 2030, BD will largely have died off except for some smaller boutique labels who may still make produce them
