I'm sure that the initial answer from M will be "use the secondary output from your 4K player" and that "when there is more 4K material available, we'll consider an upgrade". Which is actually pretty sensible.

I find a worrying amount of what I actually watch was either shot on 35mm (so 1080p already starts to show the limits of the filmstock) or worse, SD video.

YMMV.
