The director indicated in April that he was lobbying Disney to release the film with the extended color and contrast that the format allows.
"LIGHT and COLOR are such important elements of 'Vol. 2's' story, and why we screened the world premiere in Los Angeles in essentially this format," Gunn said in a Facebook post Wednesday (read the full post below).
The director said that home releases will also include a 3D version, plus plenty of extras and surprises. His post didn't mention high dynamic range, but the disc has been rumored to include thealong with the standard available on most 4K Blu-ray discs.
"We will soon have lots more exciting announcements about the home release and some unbelievably cool additional content, including something that's so amazing I've been chomping at the bit for months not being able to talk about it!" Gunn said.
A date has not been finalized for the release.
4K Blu-ray is the highest-quality disc format and so far includes over 100 releases from studios such as Warner, Paramount, Universal/Sony and Fox. Disney fans have another reason to be excited as rumors point to Star Wars being next to get the 4K treatment.
