I found an unboxing video, it shows that the digibook is brown, not green.
But now it gets confusing:
Amazon lists it with a runtime of 178 minutes, which is the theatrical version. In the video you can see that it is only one disc, but the digibook's j-card states a runtime of 208 minutes, which is the exended version.
So either the information on the j-card is wrong, or it is indeed the extended version on one disc, which would mean that it's probably a BD-66. If somebody has it, please check and let us know.
