Might Sony abandon the 4K format it helped create?
Sony has reportedly stopped shipping its last 4K Blu-ray player in Japan, the UBP-X700/K, suggesting a potential withdrawal from the 4K Blu-ray market. This follows declining support and rumors of discontinuation, though no official statement has been made. Sony's PS5 will end 4K Blu-ray disc support for new titles in January 2028.
