That is if there is still an optical drive market in the future.
Sony never made a big deal of how the PS5 can play Ultra HD disks the way they did with DVD and Blu-ray. Ultra HD sales seem a lot smaller than previous renditions. You also have a lot of content being kept behind the streaming paywall rather than getting released.
I don’t think there will be a large enough market to support 8K, backed up by the fact that a specification has been written but no one wants to go forward with making the disks and drives.
