@RonnieR15:@rein: It's always possible-- Disney actually has started doing some animation directly for the Japanese market, most notably a kids show called Fireball. That said, there's definitely no official word of such a project, and I wouldn't bet in favor of it happening either. I don't think Disney likes to be beholden to another company (in this case Square Enix) for its products.
It going to be hard to have a Anime about KH. I know that Disney is really strict on how Mickey, Goofy and Donald are portrayed. If it ever happen, it be weird to watch all the Disney character speak in jap. since I'm so used to the English voice.
@gia: Four mangas that cover the events from each of the games: KH1, KH2, KH: Chain of Memories and KH: 358/ 2 Days. The 358/ 2 Days one is still ongoing. As for the likelihood of an anime adaptation, there's the possibility, though I'd be concerned over the quality of it since a majority of video game based anime titles I've seen tend to suck.
I tried the Kingdom Hearts manga...to me, it is slightly strange compared to the two Kingdom Hearts games (2002 and 2005) that I have played. Has anyone heard any news regarding the development of Kingdom Hearts III?
