After the initial February release date, which was delayed to Spring 2016 and then later, 5pb. announced its latest delay with a new release date of March 16, 2017 for the YU-NO remake on PS4 and PS Vita.
According to 5pb., the reason for the delay has already been solved, but as a result of looking at the system and wanting to make things easier to play, and in addition to wanting to flesh things out more, they decided that a delay would be required.
Again, the first-print bonus featuring the original PC-98 version of YU-NO was to be available on December 26, but this has also been delayed to March 16, 2017 as well. The original date for the PC-98 version was supposed to coincide with the game’s 20th anniversary, but it’ll be delayed by a few months alongside the remake.
