Recently information was leaked about an alleged “Kingdom Hearts 2.9” that would be coming to PlayStation 4 before the release of Kingdom Hearts III. As was revealed by Shinji Hashimoto during Sony’s press event at Tokyo Game Show, Kingdom Hearts 2.9 is actually Kingdom Hearts 2.8, and will be the third compilation of three titles in the series that precedes Kingdom Hearts III.
The first title included is an HD remaster of Kingdom Hearts 3D: Dream Drop Distance. As it is no longer on the 3DS, it has been re-labeled as Kingdom Hearts HD Dream Drop Distance. The second title will tie into the upcoming mobile game Kingdom Hearts Chi Unlimited, and is called Kingdom Hearts X: Back Cover. The third and final portion is a chapter titled Kingdom Hearts 0.2 Birth by Sleep: A Fragmentary Passage, and will follow Aqua’s journey through the Realm of Darkness following the end of Kingdom Hearts Birth by Sleep. This trio of games will release for the PlayStation 4.
So to recap, Kingdom Hearts 2.8: Final Chapter Prologue is coming to the PS4 in 2016 and will include the following three games:
Kingdom Hearts HD Dream Drop Distance
Kingdom Hearts X: Back Cover
Kingdom Hearts 0.2: Birth by Sleep: A Fragmentary Passage
