Kingdom Hearts II.8 Announcement Trailer From Tokyo Game Show

Square Enix revealed Kingdom Hearts HD II.8 during the Sony Computer Entertainment Japan press conference at Tokyo Game Show 2015.
Kingdom Hearst II.8 is a compilation of Kingdom Hearts related material, including:

• Kingdom Hearts: Dream Drop Distance HD, a remaster of Kingdom Hearst 3D: Dream Drop Distance for the Nintendo 3DS)
• Kingdom Hearts X: Back Cover, a brand-new Kingdom Hearts cinematic
• Kingdom Hearts 0.2 Birth by Sleep -a fragmentary passage-, a brand-new playable episode tied to Kingdom Hearts Birth by Sleep Final Mix for Sony’s PSP system.

We can’t say for certain whether or not II.8 is the same project spotted on an ex-Square Enix developer’s LinkedIn profile under the title Kingdom Hearts 2.9, or what would have prompted the title change.
Kingdom Hearts II.8 releases for PlayStation 4 in 2016.
