you probably know this already, but if not, FYI eBlu already did a non-4k edition for the last steelbook for this film, the one with original graphic novel artwork, with a genuinely quite good multi-textured hard case slip. release thread here.
Weren't you asking if it would go out of stock before it went out to non-RC members? Thats what I answered. Of course 1k copies would sell out relatively quickly for a beloved movie showing up on a new format for the first time.
I have the Amazon-exclusive Blu-Ray Steelbook from Germany, that I could grab for €5 when it was on sale (last picture). Maybe I will upgrade and buy the 4K-Amaray sometime.
Plenty of Stellbook releases for this one.
