UPDATE 17th Dec 2018: Kingdom Hearts 3 director Tetsuya Nomura has responded to the recent leak, saying the biggest spoilers are not yet in the game.
Specifically, the game's epilogue and secret movie will be released "at a later date", Nomura said, which suggests they'll be downloadable content of some kind. Perhaps day one DLC?
Nomura also called on people not to share leaked videos of the game that emerged over the weekend after copies of the game popped up for sale on the Facebook Marketplace over a month before launch.
