They might’ve been a last minute thing since they couldn’t release what was originally intended for that time.
Maybe.
Hopefully the covers for the 4K OOT will reflect the original poster art and not the horrible steelbook cases. Though I would love a steelbook release to go with my TFA and eventual Rogue One blu-rays.
If they released the OOT as individual 4k steelbooks with original poster art, I would go crazy.
