It most likely will have a regular blu-ray as well. It's very rare for a 4K release to not have one. Especially if there is bonus material because the 4K disc usually only contains the movie and commentary, if there is one, to maximize picture and audio quality.
Being an anniversary release, there has to be some kind of bonus material lol.
This is awesome news as Pet Sematary is one of my all time favourite horror movies. So for this to get a 4K release and it’s first steelbook (that I’m aware of) has me very excited. Here’s hoping it will end up with some great artwork along with nice treatment
PET SEMATARY is with HMV in the UK as an exclusive at present ... as part of their Premium Numbered Spine Slipcase Collection ... View attachment 408365
... so a steelbook at least here in the UK seems most unlikely.
