My guess is it will use a fully stacked sensor. I think the issue here for some people is that they confuse and equalize fully stacked sensor with top of the line performance.
Stacking is just a design architecture. It's like turbo engines in cars. The top of the line horsepower will have turbo engines, but there are also turbo engines that don't deliver top of the line horsepower. It all depends on what makes the best business sense (in terms of cost and effort) to achieve the target performance.
And I think A1iii will use global shutter sensors. It will target the next level.
I think you are way ahead of what is going to happen soon. It isn't like turbo engines in cars. You can get more horsepower in a car by building a bigger engine, but turbo engines can often deliver just as much power with a smaller engine. For the same horsepower then turbo often let's you go with a smaller engine. Those sorts of tradeoffs mean it isn't always cheaper to use a naturally aspirated engine than a turbo engine.
There is nothing like that with sensors. No such tradeoff exists. If you want sensor scan speed, you can't get it without stacking the sensor and a fully stacked sensor especially on a high MP camera like this one is expensive and stacking the sensor doesn't let you have anything like a smaller engine, so saves you nothing. It is more expensive. If the goal is a 15ms sensor scan speed, as the rumors seem to suggest, then there is no need to use a fully stacked sensor to get there. They can easily get there with a partially stacked sensor.
I also think it is really unlikely that the A1 III will be a global shutter camera. Lots of improvement in DR is needed with a global shutter at this point and I would be very surprised if they can get there by the time they make the A1 III and I can't see them making their flagship with weaker DR especially when they can make a A9 IV with a global shutter. Expect the A1 III to have something like a 60 MP fully stacked sensor with DR like the A7 V (and likely the A7r VI). That will be a great sensor, but it will be an expensive sensor and much better suited for a $7,000 camera like the A1 III, the $4,500 or so A7r VI. If you want a global shutter A1, I am betting you will have to wait at least until the A1 IV.
