Sounds like it's a lot more than bug fixes / heat management and that “for time frame, it may require longer than you probably imagine” :

..Sony also shoots down the 8K theory inside a MILC before 2020..

Saw this video and this is just PR spin/buying time. Redesigning a camera would be a massive fail for Sony. This camera was being planned when the A7sii launched so there is no way they're "going back to the drawing board"

I'm not saying you're not on to something... but the A7SIII rumors have simply been all over the place to the point of it reaching unicorn status.

Sony themselves have sort of admitted going back to the drawing boards and postponing its release.. 

It's one thing to have a great sensor but materializing it into a stable/viable camera is another.

As for sensor data sheets, I don't want to argue with numbers but they don't always reveal the full picture (no pun intended). 

Many claimed A73 > A7S2 in low-light but really the cam got there by "cheating" with heavy use of NR at high ISO values.

Getting back to 8K i think it will be put in the Mark IV Sony cameras, just in time for the 2020 Tokyo Olympics.

That is the roadmap deadline the Japanese tech industry has set for 8K consumer product roll-out.

If Sony were to "go back to the drawing board" with the A7Siii, it would take another 2 years to release the camera. My guess is they are battling with some bugs, most likely heat management.
