I thinking about the pocket 2 rumor and the mini ursa 4,6k sensor. I think that the new pocket will still be a s16 sensor camera and probably use the same sensor of the ursa mini but with half the size (the pocket 2 will record 3.2k in camera). The increase in dynamic range of the ursa mini (13 for the pocket and 15 for the ursa mini) is cause by the increase in size of the sensor. Alexa 65 do same with the regular alexa: the dynamic range increase 1 stop. In the case of the alexa 65 is the same sensor of the regular Alexa, but bigger.
