Kingdom Hearts III demo is not planned for public release, but will be available at Tokyo Game Show 2018

Meh, with 0.2, a demo is not really necessary.

That, and it prevents data-mine leaks from possibly happening.

Thanks for sharing this with us, Aquaberry!

Ah, so a public demo won't be released then, huh? Well, that's okay! To be honest, I'm fine with that, and like Awesome Sauce said, with 0.2, there's really no need for a KHIII demo! I'm more than content to just watch the trailers and read up on any new info that Nomura and his team release in the coming months! We're gonna zero down to just six months of waiting soon, so it's no biggie!

Unpopular opinion: KH3 demo edition;

Though I did fortunately get to play the Kingdom Hearts III demo at E3, I think it's extremely unfair that you have to buy a $60 game (with a game that launched at $40 and is even cheaper now and a movie that anyone can see anytime on YouTube), especially with the fact that the current KH3 demo is very easy to use and launch with. It is a decent length, doesn't give too much gameplay or story (the one at E3 was even shorter than the one at the KH3 premiere) and  it's fun. It would especially boost the market for Xbox gamers who otherwise would NEVER pick up the game. 

I don't want to be a blind fanboy to KH, so I'm definitely questioning this decision. It's just that no KH demo to date has been done and Nomura even said the team didn't need the extra time in January and that it was a marketing decision. A month to rework the current E3 demo makes complete sense.
