I have cancelled my pre-order for now.  It seems the AF on these is not up to the D850 and D500 in terms of speed or AF tracking.  Since I am beginning to do blackwater photography, AF and CAF tracking is an absolute key aspect of the camera and not something I want to compromise on.  I am still reluctant to go to the huge housings for the D850 and D500.  So, I will be waiting to see new developments later this year from Sony.

Sensor-based AF can't compare to a dedicated AF module (requiring a mirror). It's certainly come a long way but still a far cry for the foreseeable future. I guarantee you Sony won't suddenly revolutionize sensor AF later this year.

You might be right, but then I will settle for the best that mirrorless can offer.  For now, that seems to be the A9 but Sony is rumored to have an APS-C camera coming with the same or better focusing.  That might be the best compromise in terms of size and performance. Also, don't know what the new Canon is capable of yet.  Seems like a good time to wait for a couple of months before deciding anything.

I suspect we will soon see mirrorless/live view AF out-performing conventional AF. Already it is more accurate. As well, there is greater coverage across the format for full frame, more sophisticated AF, and more AF points. These are probably inter-related. Faster CPUs probably help here. We will probably will see dedicated CPUs for focusing in upcoming pro models, maybe even the replacements for the D5 and 1Dx2, to speed things up even further.

 

A big limitation in the past has been viewing - hard to see the back screen in daylight among other issues. EVF to the rescue. Lag seems to be a non-issue now and resolution is excellent based on what I hear (will see as I have a Z6 on order).

 

Low light ability may soon or already have exceed what conventional AF can as well.
