My gut says this is the plain release, and the double dip will come a few years from now as the re-restore them one film at a time. It's what they did for the DVDs.
I can't believe they opted to save money and do the new fx for TMP in 480p. They had do know sooner or later they were going to need a high def transfer of it.
So what now, they re-redo the effects? Nitwits.
