Thanks again to everyone who helped me and all of us realize this dream. I'm curious to see if Universal uses the original 5.1 or a remix for the upcoming 3D re-release. One thing is for sure: the trailer's 2D image looks to have improved vastly over the Blu-ray video master. With any luck, we'll get a nice, new Blu-ray as well!

I'd assume they'd continue to use the remix. I don't think that they'll make a new encode for the 2D BD video master (to save costs), but they'll probably issue it on a nice 3D BD. If that happens, one would have to extract the 2D image from the 3D BD for a high quality Jurassic Park. I'm just speculating, of course; this is what happened to Beauty and the Beast. Time will tell.
