I bought the Shogun Flame as high speed raw, for me, was a 'nice to have' rather than a necessity. The situation is thus (on the Flame):
4K raw to ProRes/DNx** via SDI
2K raw also
You can also record HFR using the end trigger on the FS700 and output over HDMI to the Shogun to get 8bit 4:2:2 to ProRes etc.
The inferno supposedly offers 4K raw to ProRes etc at up to 60fps as well as raw to CDNG.
