There was a 6 disc special edition that was released only in Japan which had the theatrical cut, so that would be both movies and the trailers. The set also included the 2 disc versions of Planet Terror and Death Proof that were released everywhere else and I think there was a disc of extras exclusive to the Japanese release. It was a pretty cool set but it cost upwards of $70, so I didn't get it.
Bunch of bullshit if you ask me, Grindhouse should have been released on DVD like that everywhere
I heard they were suppose to release that same edition that came out in Japan. Of course this was well over a year ago and it was from the same source that said Kill Bill: The Whole Bloody Affair was coming out and that never happened.
