No, I was being serious, how many versions are there?
I'm hearing steel box, and mini Enterprise.
Or do you mean blu ray or DVD?
In the U.S. there are versions:
1) Single Disc DVD version in standard case
2) Double Disc DVD version in standard case.
3) Single Disc Blu-ray in standard case.
4) 3 Disc Blu-ray in standard case.
5) 3 Disc Blu-ray in Enterprise case.
6) 3 Disc Blu-ray in steel case.
That's all I can think of, and I may be wrong on one or two of those, but I can't seem to find all the information together.
