Kingdom Hearts director Tetsuya Nomura has promised that Kingdom Hearts III will provide closure to the trilogy’s story, but added that it won’t signal the end of the franchise as a whole.
?As a core game, this is finally the third, and 10 years have passed. I couldn?t call this a trilogy. There have been so many spinoffs. In ?Kingdom Hearts 3,? the battles that the characters have been fighting for the past 10 years will come to a conclusion. That is the plan. But the series will continue. Only the particular enemy they have been fighting the past 10 years will come to an end,” he told the L.A. Times.
Nomura also mentioned that fans who are interested in how Kingdom Hearts III will play should play Kingdom hearts: Dream Drop Distance on 3DS.
