It's good. It's just Scott Mosier, Kevin Smith, and Vincent Periera this time. No Mewes, Lee, or Affleck (the guy from Phantoms).
Just like the title says, they do get a little more technical. They elaborate more on casting, the controversy, locations, shooting in Super 35 vs. anamorphic, the shit demon FX, etc. It's a worthwhile listen, better than the track for Jay and Silent Bob Strike Back, actually, IMHO.
I believe the deleted scenes total about 90 minutes of extra stuff (including intros by Kevin Smith and Co.) There are also a couple of promotional pieces, outtakes, gag reels etc. that probably total about another 1 hour of viewing.
Oh, and there's also a very disturbing easter egg in Jason Mewes' bio.
