If you were hoping to get a Kingdom Hearts collection or a Kingdom Hearts 3D: Dream Drop Distance HD remaster version, you are certainly in luck. Sony has announced through their TGS 2015 press conference that they will be releasing Kingdom Hearts 2.8 for PlayStation 4.
Don’t worry, it is not something else. With 2.8, you are going to get a number of things including a Kingdom Hearts 3D: Dream Drop Distance HD remaster, Kingdom Hearts 0.2 Birth By Sleep: A Fragmentary Passage, Kingdom Hearts X Back Cover and of course the new Kingdom Hearts 2.8 Final Chapter Prologue which brings new content.
Out of these we know what each one the contents of the new collection mean apart from the Kingdom Hearts X Back Cover because that is the name of the browser based game and a back cover makes no sense right now.
One thing that you can be certain of is that the collection is going to be a treat for the eyes; it is looking really nice and I would love to try it out on my PlayStation 4.
For Kingdom Hearts 0.2 Birth By Sleep: A Fragmentary Passage it was apparent that you will be pursuing the story of Aqua. However, nothing was made official on that.
Keep checking back for more on Kingdom Hearts 2.8.
