I think Zombie is right about the Blu-Ray release of Star Wars. The first release will be mostly bare-bones, with maybe a few interesting extras. Later Blu-Ray releases will have added extras, with a small possibility of the OOT.

However, if there is a DVD ONLY box set planned in the very near future, I don't see how it will sell without the OOT or some really, really interesting deleted scenes. The DVD market has been saturated at this point, so any DVD releases will have to appeal to hardcore fans.
