If they make a Kingdom Hearts 4 for the love of the seven drop Goofy an Donald from the main cast.

Well, based on the secret ending, it seems they may not be in the game but who knows.

Edit: Or maybe they'll be in it, they just won't be apart of your party. I can't deny Donald and Goofy were useless in battles plus as usual I found them annoying throughout the story.
