Sony Pictures just sent a press release announcing officially the new Ultra HD Blu-ray versions of Ghostbusters and Ghostbusters 2 for June 7th.
This has been rumoured for a while as there was already 4K remastered Blu-ray versions available from Sony. Both movies will provide a Dolby Atmos remix and HDR picture.
I updated the list of Ultra HD Blu-rays and list of Dolby Atmos Blu-rays on the site.
