The PCI e XQD cards don't look as good as a TB memory stick would be, or card based on parallel TB ports. It is only 1GB/s? That's slow. 8k 4:4:4 16 bit raw 24fps (not bayer version) would be 192MBx24, under 4.8GB/s and x10 for high frame rate/3D. Even if you use bayer that's still under 480GB/s/3 under 160GB/s, or under 1.6GB/s at 24 fps, or under 3.2 or so at 50fps, or under 9.6GB/s 4:4:4. So, this talk they use about how good it is for uncompressed raw cinema recording, isn't so true in the long run, more a pocket camera thing were you don't expect top end recording modes like the Japanese are talking about (but come next decade new processing technologies, even that could be possible).
At visually lossless high frame rate high bit depth 4:4:4 you maybe achieve visually lossless at 20:1+ as these three separate things (and incresased resolution) make clean frames more compressible, so 8+ -24GB/s. Using Redray codec technology (only a guess, as I would have to sit down and work out figures,) it might be 800MB/s to 2.4GB/s.
