I honestly think that they're going to gauge the demand for the OOT based on the 9/12 DVD sales, and then decide whether or not it's worth doing new transfers to put them in the "ultimate box set".
I mean, isn't it kind of risky for them to sell yet another set of DVDs less than a year before they're planning on selling this 30th anniversary mega-boxed set?
I really can't see myself buying that whole thing, including the PT films (which I don't want) and ANOTHER set of the SEs (which I don't like and by then will have already bought twice) just to get a few "deleted" scenes from the OT.
