So the current DVD release would effectively be considered a Director's cut, without edits, right?
well, in a somewhat ex post facto manner, i guess it is, if by "director's cut" we mean a longer version of the film.
then again, with regard to an extended version of the film, we have to remember that Gibson had to deal with very little intervention from movie bigwigs in making the film. or probably none at all. nobody even wanted to lay a hand on the film. so i doubt that the version of the film originally released is not the total consummation of Gibson's vision.
if that is indeed the case, then all we can hope for are commentary track(s) and additional supplemental material.
