File size is a major limiting factor in high speed video and to a lesser extent convenient ultra HD digital film. At 3840x2160 (basic 4k) uncompressed 10-bit video 1 frame is about 250 MB. An hour of footage at 30 fps then is about half a terabyte. At "only" 1000 fps you would burn through an 8 TB SD card in... 32 seconds.

You'd need some way to cache that video, though, because it'd take 24 hours to write 8TB at SD card speeds of 80 MB/s.
