which was Kingdom Hearts III. However, Final Fantasy XV was still his primary focus, preventing him from starting production on Kingdom Hearts III. He later noted that Kingdom Hearts III would not see a release until after 2012, due to his continuing work on Final Fantasy XV, regardless of the tenth anniversary of the series occurring in that year.
