Yes, this seems to be the Fairchild APS-C sCMOS 2.0 sensor (LTN4625A), which is basically the perfect sensor right now: same design as the sensor in the pocket, but APS-C and 4K.
The fps limit is probably on the processor, not the sensor (even the sensor in the original BM could do 150 fps or something like that, but the BM processor wasn't able to work that fast).
The Ursa Mini looks KILLER, at a price that makes the C300II seem laughable (even the FS7, actually). Eagerly awaiting more details (I need a m43 mount so I can put a speedbooster and make my FF lenses work as intended; and I can live with a much smaller camera, so I hope they'll have stripped down versions too: do we know the sensor size for the drone camera? edit: yes, we know: s16, 13 stops of DR)
I'll have an eye out for your posts after 9:30 AM, my friend... yours should be particularly interesting.
