Sorry -- No way is the additional content coming to the US. You're forgetting that Squienix would need to localize the whole darn thing and that'll take a bunch of resources. Given the co. is saddled in development for PS3, 360, Wii, and DS, the thought that any people would be moved to work on a GH version re-release of KH2 for a now-past gen console ain't happening.
Now, if this were Capcom, may be I'd venture to say possibly, but then again, that might explain why Capcom's localizations are often so bad (and let's not even start on the voice acting ...)
