idk, but I had a press thing that came that said this and 4k. So unless 4k was an error then its coming too.
I used the link in the op and they list a 2 disc version and a 3 disc version, both with a June 7th release date and same price.
Will keep an eye open as really liking that slipcover, fingers crossed for a 4k release.
No 3D either (even though it was natively shot in 3D)
