I think this whole "bonus material" crap is a test, and the way Lynne Hale's response is so carefully worded ("The 1993 Laserdisc masters represented the best source for providing the original versions as DVD bonus material"), leads me to believe that they will have new transfers done of the OOT as non-bonus material .
VERY good point, Mielr, and I too get the impression that one probably should read between the lines with his statement.
