Note: he also made a more detailed 'equivalence' based case for better PDAF performance on FF here, where he said:
We find that autofocus performance is strongly sensor size dependent for equivalent cameras.
He only makes a statement about accuracy, not AF speed, though.

The term "performance", taken out of context may indicate faster focus lock and/or better tracking, but the sensor size obviously has no influence on this kind of AF performance.

Biggger sensors help with AF accuracy due to the fact that for the same output size (print or monitor display), the enlargement factor required for the bigger sensor is smaller. As a result all image imperfections at the micro level are less visible.

This includes the small AF focus errors that are introduced by every real world consumer AF system. Hence, given the same AF system on an APS-C and an FF camera, the AF focus accuracy will be higher by a factor of 2.25.

Indeed. It's an interesting topic. One assumes that FF delivers a degree of 'equivalent' advantage, but in practical terms a lot depends on the tech deployed to make the AF happen I suppose.

Does the AF advantage of FF for PDAF translate into mirrorless FF CDAF, for example? Then you have all those cameras (mirrorless and PDAF, FF and even M4/3) with ultra-low-light (-3 EV, -4EV) AF systems that must also complicate comparisons that equate sensitivity and/or sensor size with AF performance.

Look at falconeye's article you referenced. The answer is "no, not quite". The AF accuracy advantage when using CDAF, is just a factor of 1.5.

There is no D7500 and the D610 AF system is not very impressive. The D610 has the same AF system as the D7100 including the AF point array which is why is looks so small in the OVF. Its a terrible camera for AF tracking and low light AF.
The D600 had incredible AF in my experience, but my other experience is really only Pentax + Sony. Low light AF was great.

Other than the grid of AF points, I can't tell the difference between the D810 and the D600 AF.

Assuming Ricoh releases the full frame using the 36mp Sony sensor with improved DR, noise, and ISO range, selectable AA filter like the K3, dual card slots, crop mode enabled, ~7fps, WR, and the features we have on the K3 what would you be willing to pay for the body only? Not with the kit lens offerings, just the body and the normal stuff that comes with the body. After voting say what your reasons are for choosing what you did if you don't min, and even say the exact target price you're looking for. Thanks.
Because I have some superb SMC Pentax-A prime And Tamron Adaptall2/SP lenses with PKA adapters, I have been patiently waiting too long for an affordable FF Pentax to arrive. Letting the Nikon F700 pass with eyes now looking backwards on the Nikon F750. All this against the acquisition of a couple of superb Lumix compacts both with Leica lenses for less than £50 combined. With bullion prices slipping, maybe a dozen full sovereigns would be more attractive. Perhaps someone can inspire me to rekindle my enthusiasm; if I could hire a FF body for a month that might help.

It will all depend on what kind of camera it is. I hope to see a camera with the capabilities of a K-3 for a price of $1999 at release, similarly to Nikon D610.

Ricoh has been mirroring the prices of Canon and Nikon offerings, so I think that's roughly where the price will be.
I could also see them releasing a flagship model for $2999, and a cheaper one later.
