In a year or two? Maybe in a decade or two.
Who would store a single movie on 2,000 tapes?
I have to point out that those numbers as realistic as LTO's advertised 2.5x compression ratio. 120 fps? Even 48 fps has only been in a couple of films, 24 is still standard and all of the old 60i except sports have moved to it. 3 images? 3D is niche despite years of effort, being phased out, and that's still only 2 images, a left frame+difference (easier to compress). 8K is years, maybe decades from penetrating the studio market; they're still grappling with 4K right now. And typical movie length is 1.5 hours, not 2 hours. I don't work with audio as much, so I can't say how real-world 22.2@192 is.
And while you can blithely say "before compression", every recording format is compressed these days. Some shoot straight to pro-H.264 (444@12 bits), some use proprietary codecs, but there are none that aren't compressed in some way.
Real world data rates of current RED cameras at 4K are about 1.5Gbps, and that's likely to only slowly increase, not massively jump. Even for a 2 hour movie, that's 1.3PB, not 28PB. That's still huge, it's an order of magnitude less, but even at a mere 100 tapes, who's going to store a movie that way?
More likely it's going to be recompressed to fit into a few TB and left at that, so one tape or one HDD will suffice.
