I'm not sure about this but I heard that the ending in the US version is about 10mins shorter than the Int. version! The reason (I heard) for this is that the ending in the Jap. version (which was first) did not exactly make sense, so they lengthened it for the US version, but then it still didn't make enough sense so they lengthened it even more in the Int. version.
