If the GOUT was anamorphic, then it would sell out overnight; but the caveat for Lucasfilm is that if the OOT sold like hotcakes, then the "official" vesrion of the saga would suffer and go against their plans to eradicate the OOT from the collective consciousness of the general public. It is their gaol that 50 years from now, no one will remember the OOT and everyone will unconditionally accept the SE and PT.
