This is probably true. The sooner the better.
This kind of hype from Sony is what gives resolution numbers a bad reputation.
What gives the quality of higher resolution is the higher resolution sensor in the camera that is able to capture and resolve imagery by "dividing" the captured objects into "smaller squares", preferably with a sensor that has more pixels than the intended output resolution of the finishing edit.
When Sony use a 6K~20MP sensor that use 17,6MP part of the sensor for active image capture and claim it is 8K (=33MP) or can be a "true 8K camera" just by a firmware upgrade we know that something doesn't add up.
A 20 megapixel sensor can in no way resolve anything close to what a 33 megapixel sensor can.
Its active pixel area of 17,6 pixel is about half the pixels of the 33 megapixels of a 8K format.
What Sony does is to take the 20MP sensor (17,6 active capture pixels), do a marketing pixel count in a way that if everybody counted pixels that way there would be a lot of "8k cameras".
Then they apply a Pixel-Shift process technology in the new Firmware in the same way they have done on "HD" video cameras that often doesn't have a real resolution HD sensor, and end up with a "8K" claim that in no way is even close to the minimum required 33 Megapixel that is the basic foundation on the term 8K.
This is the truth of the Sony F65 8K pixel count claim before the latest firmware upgrade. The F65 has not gotten a new sensor with the new firmware; http://camerarentalz.com/sony-f65-6k-sensor/
So Sony already now starts to dilute the understanding of what minimum resolving quality a 8K digital motion camera should have, before the time comes when Real 8K digital motion cameras will be made, and that just for being able to do some promotional hype for a camera that should be able to stand for its own real merits.
