The currently used af-c tracking in dslrs usually bottlenecks at the processing unit. One of the reasons they could improve the same af module with the k1 II update compared to the k1 I, same reason why the D5 tracks better than the D850.
If they are able to produce a Pe tax compact style camera with faster chips than bigger competitors, I am not sure about this.
As long as they did not find a completely new algorithm this statement just seems very unlikely.
I would be ingerested to read a Petax source about this, esp from when it dates back is a very interesting information.
I don't think it is an entirely different topic.
With a modern DSLR, it needs to focus like a SLR when the mirror is down, focus like a mirrorless when the mirror is up, and somehow transition between the two.
In some ways, it is the worst of both worlds in terms of complexity.
