The only other thing from KH3 that could possibly blow me away (at least as far as a World) even more at this point would be if Harry Potter/The Wizarding World (it would work so unbungalievably well, and after all, Disney is buying A LOT of properties these days (let alone the fact that they DID have TV rights up until very recently, and were originally going to have The Wizarding World Theme Park ...
and or Disney's Dinosaur is featured as a World (or if not KH3, as soon as possible in one of the next console KH games). Now is definitely the time to feature the latter, as it will be presented in its absolute best game format, and would offer a great variety in both gameplay and environment. It would also be a lot easier to design than The Pride Lands, even with the next generation graphics and engine, and again would offer up a lot of neat things you could do with the World's environment, such as breaking the ground to find water and destroying pillars in the cave (like in Dinosaur's own Action Game for PC/Dreamcast/PAL PS2), as well as mini games in the Nesting Grounds (and maybe on Lemur Island
Japan hates Lilo? Hmm, maybe thats why its only been Stitch and NOT Lilo in KH so far....
