Just skimmed this and yeah, this basically sums up a lot of things. I can assume that for any Kingdom Hearts release (especially in North America) there has to be a whole deal of contracts to be issued and signed, which is supposedly why they are reluctant to release any of the Final Mixes. Not to mention that they are working with this All-star cast, it would be a more difficult grasp to keep them on board with such ports and re-releases. This would partly explain why Re: Chain of Memories NA release was a year and half after its JPN release. I believe that Disney itself is a whole licensing fiasco, with one of the most obvious reasons being the absence of the Tarzan property. Nightmare Before Christmas, Winnie the Pooh, and even potential Pixar worlds would need such careful and intricate contracts to distribute their rights. It's really a sad thing to see how this factor can affect so many other factors in the quality and sales of a game.
I wouldn't mind that they just subtitled the games, if it that meant that the game were to be realesed. I Know is kinda strange for you guys at US, as you're not used to seeing things subtitled (movies, games, etc) and not in english, as it is a "universal language", but I grew up seeing movies, games , comics, books in foregein languages, so the concept of playing or seeing a movie all subtitled isn't that strange to me. I guess a translation would need less checking, but then again maybe Disney don't want to launch a game whithout their voices, as they already "showed up in movies, etc.." and people would not aprove it, like to think Mufasa's voice being other than James Earl Jones? (The force is strong in you >(! ) It's hard, but I guess is not as hard as capom games (from ps1) , KH games are way newer and should be simpler to work with.. even thinking all these different movies toghether.
