Earlier this week, Square Enix confirmed that Kingdom Hearts III will release on January 29th, which is later than the 2018 release window that had been confirmed a while back. According to director Tetsuya Nomura, the release date has been decided following suggestions from a variety of parties.

Speaking with IGN at the E3 2018, Tetsuya Nomura revealed that hardware manufacturers, marketing teams, and sales teams felt that a 2018 release date wouldn’t have been good timing, which is definitely true considering the titles releasing in the final few months of the year.
