I just added Trailer 2 and 3 for the Disney / Pixar film Coco, which will arrive in theaters on November 22. These are the official studio 5.1 mixes, and can be found at the Coco (2017) page.
I have had a number of people ask about 3D trailers. It looks as though I will not be obtaining any more 3D trailers for theatrical films. I am also sorry to say that the largest manufacturers of 3D displays – Sony and LG, have announced that they will no longer be producing 3D capable units. It appears that the future of home cinema does not include 3D.
