Nomura is still deciding on the Secret Movie and ending for Kingdom Hearts III, which will finish the fight with Xehanort but not end the series

[The Transcendent Key 12,109]

Oh God....oh good God....oh frickin frackin yes!!!!  We've got a secret movie confirmed, since Nomura said that he's working on it!  Gahhh, I'm so psyched!  I wonder how Nomura will end up writing the ending and secret movie of the game, though?  Ooh, this is going to be good!  I don't even know what to expect!  Nomura, you sly fox, I know you'll surprise us with whatever you have cooked up in that marvelous brain of yours! :')
