I have linked a comparison at ISO100. That's a difference with noise level in the shadows, which defines the dynamic range. In that case (all images downscaled) it is similar to DxO's "Print" tab comparison.
Sure and I agree, question is more if you are after low contrast pictures like biz-engineer or otherwise rely on tripods and picture stacking and then the reduced dynamic is of no importance...

Or if you like HDR, to capture wide dynamic range scenes

I admit myself that 50MP is not that interresting, in particular compared to 36-42MP and that the dynamic range may be more usefull, but that depend a lot on your practice.

You stretched the K-3 AF points to match the 1Dx and D5 matrix, in that case, of course, the K-3 AF has the same frame coverage as any camera ! Did you try to layout the K30 AF module (with a bit of mouse stretch) on top of the D5, I sure both AF modules could match.
The stretch aims at matching the screens, not the matrix. beholder3 took the precaution to write a caveat: "if they manage to scale up the whole coverage from APSC to FF using different AF optics."

Ricoh filed a patent on this; has anyone kept a link?

Yes, for the K-1 we need to hope for a new solution.

The coverage in the K-3 already is as depicted.

But they very likely match, the sensors of K30 are not as many, not as precise, but I think they cover about the same surface in % as a K3 rougly. Now does that make the K30 AF as good? Hell no, my father just got a K3 and can tell you there a great difference.

Ok D610 body reused an APSC sensor without any tunning and change and so the covered area is very small in %, but this doesn't mean that all other manufacturer have to do the same.

This one ?

Ricoh's patent for contrast AF by the AE sensor | Pentax Rumors

Actually we all should thank the editor of PentaxRumors.com : 36 news in about as many days is a significant and great performance...

Was quite obvious to do except the sensor is not yet high resolution enough... but I guess it would be quite easy to get a few MP sensors, the problem would be only the processing power.

No, the one about an optical device in front of the AF module allowing to expand its coverage.

Yes ^^ [EDIT], and I want to let some time go by first, then read the entire, evolving thread as a poster argues about facts.

Yes, thank you. I bet something like that is used in K-1. And imagine what you would get with a medium format camera!
