Even though I'm REALLY excited for the game and excited for the possible new worlds for kingdom hearts 3, I REALLY hope that there will be some nostalgia in kh3 because it has been in my favorite kh game, kh2.  I'm NOT saying that there shouldn't be any new stuff in the game. I know that the stuff I'm about to say is a little selfish, but I think it would be nice if they decided to show SOME old worlds from the previous past two numbered kingdom hearts games so that the nostalgia that I got from kingdom hearts 2 would be flowing back into me.

 

Honestly I don't care if they don't do this or not, but maybe as long as all of the new worlds are really innovative and unique, kind of like the worlds in kingdom hearts: Dream Drop Distance, I probably won't be complaining about the possible against that could have been in kh3.

I'm pretty sure that we'll see plenty of old worlds returning, just with a bigger scope than in previous installments, ya know?  Just look at Olympus Coliseum!  From what I can tell, the world shall mostly take place on Mount Olympus and its outskirts, which is the only place we haven't seen in the series yet concerning Hercules!  I'm sure there'll be plenty of nostalgic nods to every fan that'll probably be "blink and you miss it" moments.

They'll probably have some scenes from Kingdom Hearts 1/2/CoM/BBS/3D redefined in Kingdom Shader graphics either as flashbacks, or, further explanation.

Nostalgia will definitely return and be prominent for this installment.
