Every week the content of Japanese magazine (Famitsu and Dengeki PlayStation) are basically the worst kept secret in all of Japan, as they tend to leark about two days early.

Twitter user aibo, who certainly isn't new to providing Kingdom Hearts information, mentioned that an interview with Director Tetsuya Nomura reveals that Kingdom Hearts HD 2.8 Final Chapter Prologue will support 4K resolution (although there are no info on whether it's upscaled or native), logically on PS4 Pro.

While this kind of leaks should be considered a rumor for the moment, we'll most probably get confirmation tomorrow at midnight Japan time. Considering that 2.8 isn't exactly a visual miracle, the information is definitely not farfetched.
