That's a lot of conjecture. This isn't Jaws, and just saying 'There's probably some edits" doesn't mean there will be any, and from every indication so far, EVERYTHING that was on that LD is going to this DVD set. All of it. There MIGHT be a new commentary track, but I doubt it, simply because Jackson seems to have been WAY too busy on Kong to have sat down and done a full commentary.
I'm guessing MeBe is simply waiting to see what's actually what before pressing forward.
