For some reason I have a feeling the UK may be getting the DVD a month earlier than us. Since I don't want to watch an HD stream for a while month, I guess I will have to import the DVD from Amazon.uk.
tl;dr: For the US, July 3rd is the digital HD release and it comes out on Blu-Ray/DVD/On-Demand on the 14th. It includes a critics' commentary, an interview with the composer, and a poster art gallery.
