Check out the latest Kingdom Hearts HD 2.8 Final Chapter Prologue trailer. It includes never-before-seen scenes depicting a mysterious meeting of the "Foretellers", the five Keyblade Masters from the Kingdom Hearts origins movie included in the compilation as Kingdom Hearts χ [chi] Back Cover.
To be outright honest, if you don't know what's going on, do be discouraged. Most of us don't, but I'm sure it'll make sense when we have the game, which will be available January 24, 2017! Mark your calendars, kiddies, it's finally coming.
