4K Blu-Ray was released a few days ago. Has all three cuts, the original mono track, and an isolated score track (only on extended cut, I dunno why tho)

And 1080p for us non-4K people.

Might as well get both since Arrow rarely does dual format releases with 4K and Blu-ray disc anymore.
This disc is still nice, too. Will add it to the Blu-ray release.
