Just received my copy today, and interestingly it seems to have three cuts: the first disc contains what it calls the "original theatrical cut" and the "US theatrical cut", and then the director's cut is on disc 2.
The two cuts on disc 1 seem to be completely separate transfers, with the US cut being hard-subbed
Edit: I've taken some screenshots to compare - they're just taken with VLC and I wasn't able to exactly match the frames so take them with a grain of salt but hopefully it gives some idea

Edit again: another set of screenshots showing the subtitles. The US cut subtitles are hardsubbed (i.e. encoded onto the video) but the other two are standard bluray soft subtitles.
