The sensor in the FZ1000 is 20 MP on a 1 inch sensor. I own one, it is a great camera and I love it so lets get that out of the way from the beginning.
When we shoot 4K with the FZ1000 it uses only 8MP from the center of the sensor and the signals from those 8MP's feed directly into the processor. Therefore the light procession capability of the camera, at 4K is the same as it is at 1080P. The signal to noise level at 4K is teh same as it is at 1080P which is to say OK but not really very good. These days ISO 1600 is pretty marginal for both stills and for video.
If Matsushista, AKA Panasonic were to design a 1 inch 8MP sensor and use that "reduced resolution" sensor in the current camera with the current electronics of the FZ1000(obviously there would have to be detail signal level clean up) several things would happen.
First the low light capability of the camera for Still Photography and for Video would improve dramatically. Each pixel would be 2.5X larger than in the current FZ1000 and that would translate into dramatically improved low light performance.
The current lens and how it operates (other than turning off the lens retraction after 15 seconds which I personally want) would work perfectly with the 8MP 1" sensor.
With improved low light performance we could shoot at a minimum of 2 stops or perhaps 3 stops less light and still get great photos which would allow us to shoot at, for example, 250 or 500 of a second where we now have to use 60 or 125 of a second. That would translate into sharper photos and better quality video.
Sony did just this in their Alpha 7S and that camera delivers remarkably good video and stills with very low light capability.
Finally, if they were to design and have manufactured an 8 MP 1" sensor the geometries of the sensor would be significantly bigger which would allow for less error in its parametric performance and less sensitivity to defect levels which would translate into higher yield.
Now, I know the pixel peepers will scream that they don't want to give up their 100% looks at the images so, hey, don't buy the camera but to those of us who make our living shooting images and making videos the camera would be near perfect. The 4K video feed from such a camera could have very fast shutter speeds and therefore a lot more useful video feed for 8MP stills. Moreover, in shooting more than 1000 weddings, 500 of them digitally, there has never been a situation, other than the formal family photos, where I have had any need for a higher pixel count than 8MP.
Unfortunately I believe Sony supplies the FZ1000 sensor to Panasonic but who knows, Matsushista could make such a sensor if they decided to. They have several high functioning and well engineered manufacturing areas that could turn out such a chip.
