Maybe that's exactly why the prequels haven't been released individually: They know Eps I and II wouldn't sell nearly as well as III.

I'm the crazy guy who would buy all six films on blu-ray if the theatrical cuts were included. The blu-ray of RotS already is the theatrical cut if I'm not mistaken.

ROTS is the original version yes, and I'd definitely buy all six if the OUT was included. I honestly don't think we have to worry about that though. If Disney has to spend time and money restoring the OUT they won't want to overprice it so much that they'd lose customers, especially since the complete saga has already been released and most of the people who would buy the OUT wouldn't want the prequels anyway. If they release the OUT before Ep. VII, they will want to package it and advertise it in a way that will get people to impulse buy something they've already bought since a lot of people already own the SE's on blu ray, but that's just my prediction on the subject.
