Some fans are also hoping that Square Enix are keeping a few surprises up their sleeve, such as characters that nobody would have guessed getting included in the game, as well as interesting gameplay changes. The latter part would actually make a lot of sense given how much time has already passed in the franchise.
There has been some criticism against Square Enix for that precisely, but many fans agree that it’s better to wait longer and get a more polished product instead of seeing a rushed “Kingdom Hearts 3” that will leave a sour taste in everyone’s mouths.
That’s an impression that the studio will never be able to erase, and people will easily lose trust in the future of the franchise if Square Enix were to go down that way. So the fact that they are taking so long with the development of the game is actually most probably a good sign.
Last but not least, it’s also possible that Quinton Flynn isn’t telling the full truth, and this could be an intentional trick by him and the studio to mislead fans in anticipation of a major surprise reveal. That’s, of course, an idea perpetuated by the more hopeful members of the game’s community, but we wouldn’t be surprised if Square Enix really did have something like this planned. The studio has a long history of positive interactions with their community, and they know how to get everyone excited about their work.
