Call me biased, but I don't really wanna see actual Disney characters in XIV, but the FFish ones. Instead of Donald, Goofy, and Sora, we get Riku, Kairi, and Sora. I'd even be happy with just Sora making a solo appearance. That should be easier not only because Disney Characters in XIV would be too weird, but SE owns Sora and co. or at least has more control over them.
