I'd suspect more change than a K3-III if history is any indication. K3 vs K5 was a major change as K5 vs K7. On the contrary K5-II vs K5 was just low light AF and K3-II vs K3 was just GPS and pixel shift. I'll not buy a K3-III in term of feature with just a bigger buffer or tweaking to get same AF as in K1, honestly.
I suspect we will get a K70/KS2/K1 mix that is an articulated screen of some sort, maybe the third whell and ergonomics of K1 and a new sensor, maybe the one of K70. The AF algorithms unfortunately may not be better than the K1. And of course wifi.
But if it is only that, honestly that mean there basically now reason to buy one. We also need significantly better AFC too as well as significantly better high iso to make the thing really differentiate itself. For the sensor I am afraid, Pentax has an history of keeping sensor for long time and using more basic one than the flagship competition. For example D810 has 50iso mode and A6300 is BSI...
For AF, they should go past this 33 AF point PDAF. They need 50+ point with a wider area covered in the frame and further tweaked AF algorithms that simply perform better.
I agree that in the end, the K3-II successor should have D500 has objective, not K3-III, otherwise that will not sell well and with K3-II that will be not much more than 600€/$ to buy, it would not help Ricoh one bit on the financial part.
But ultimately, this is not a K3 successor, but I wait for something that would be a mirrorless K-mount with good AF and with small/light profile. 400-500g instead of 700-800g.
