That's a nice change for Shout Factory. Off the top of my head, I think this is the first time that they've released a TV version in the movie's correct aspect ratio. Earthquake, Halloween II, and Two Minute Warning were all 1.33 (and HII and TMW were standard definition).
Alot of King Kong was sets but I don't mean physically being there. Even if he's just visualizing it in his mind or on a computer monitor, he's still created a whole world in LOTR, KK, The Hobbit, and even The Lovely Bones.
Personally, I think he falls in love with his movies and he wants to spend as much time there as possible. I think his King Kong is crazy long but I love the world he recreated so I'm cool with it being crazy long.
I want to say that Shout generally announces that kind of thing when they announce the rest of the special features (which is maybe two months or a month and a half before the release).
I love Peter Jackson's version but I have to admit that I may buy this one just out of a love of 70's movies and to see if this is as bad as I remember it being.
