Just a little discussion topic I thought of. 

 

Do you guys think that the world completion in KHIII will be like Kingdom Hearts I's where they must physically lock the keyhole of the world, or do you think it will be like Kingdom Hearts II's where they must have a Key Item i.e H.B.R.C Membership card, Beast's Rose, etc?

Locking or unlocking something w/ the keyblade. The usual

That's an interesting question. I would think it would be like BbS where they just show the world completed, but who knows?

Sora: Well guys, it looks like that Key to Return hearts isn't here. Let's move on to the next world!

 

seriously though, i hope it's something to do with locking a keyhole.

actually are keyholes even going to be relevant anymore since the new goal is to find the key to awaken sleeping hearts (whatever THAT is)

i guess the keyholes will get bumped down to second priority, at best.

I don't think it'll be like either of those. The gist of the game is that they're fighting a war, so the way that the worlds will probably have to do with that. I think that each world will have some sort of objective that Master Xehanort wants to complete, and Sora and the others will just have to stop him.
