Interesting information.
My bad, I thought they would be able to record video on SD cards at least (SSD on board on Inspire 2). Therefore, they could be a curious GH5 competitor with 4/3" format, 4K/60p, still a chance for V90 SDXC route (= 720Mbps; ProRes begins at 500Mbps, without mention V60 cards for ProRes LT or 1080HQ at 220Mbps).
Pity, that said, they're losing a fine chance to be a competitive camera company.
