As I said the Alpha SLT and the A7R III are hybrid cameras with an interesting engineering solution to AF speed. They are are very fast, DSLR fast - much faster than a regular mirrorless. But they do have, as everything else does compromises and limitations. One of them is reduced low light performance. Another is the fragility of the mirror and they aren't, strictly speaking, mirrorless cameras.

When I want high AF performance and very low light operation I use the D850; when I want the best color/detail possible and I have the time for proper setup I use the Z7. My investment in F mount glass is so great as to make a switch else unlikely; except perhaps to medium format such as Hasselblad or Phase1.

I am going to again put in a plug for the Olympus OMD mirrorless system. I picked Olympus over Sony for a number of reasons, some of which are light weight, massive lens availability, superb feel and comfort when photographing, nearly instantaneous AF, etc. Also 11 x 14 and much larger enlargements are incredibly sharp, even at higher ISOs. I even switched from Nikon and Canon with no regrets.

I am not in the market for either one...not really waiting as in anxiously waiting, just enjoying the current DSLR tech...perhaps in a few years as tech progresses and improves, I might jump to either Nikon Z, Fuji or Sony depending on what choices exist at that time. I think in 2-3 years time there will be some amazing choices from all of them.

Mirror will not replace DSLR's, there are too many people with DSLR and legacy lenses. But If I was starting now, I sure as h*ll would be in the Sony system. Even the consumer level cameras are superior to the consumer DSLR's.
The simple answer to a complicated question. and one where there is no answer. If you want to read 8 pages of meaningless talk, be my guest. I think that this question has already been decided.

There already are Amazing choices from all of them!

Mirror Will replace DSLR’s eventually! It’s the future of cameras I believe. Eliminating the prism and the mechanical flapping mirror will save much $$ in the production process and manufactures will endorse it exclusively in the future. I advantages of mirrorless versus DSLR is a no brainer now! Mirrorless Wins!

I know what you meant, but ....

the lens on the left was manufactured 1964-65

the lens on the right was manufactured 2016-current

so technically these two lenses "span half a century" all by themselves.

I'm not sure whether Nikon's history of lens mounts is good or bad for them. Yes, you can use a fifty year old lens on a modern Nikon camera {as I can use either lens on any modern Pentax camera}, but that compatibility complicates designing an adapter for a MILC, while that task is much easier for Canon.

MILC's are better at some tasks {for example, my Pentax KP is very good at low light photography, but some times I have to use the LCD to get the job done .... with MILC it would be much easier}, so I really don't know what the market will decide. It will be interesting to see how it all works out. My KP will continue to get the job done for me regardless of what others purchase.

Even a current review from September of this year top-rated the now five-year-old Sony A6000 as still the best value for the money among mirrorless cameras.

When a "replacement" comes out, Sony very cleverly keeps the old camera available but lowers the price, so they are in a position to deliver 'value' to those who don't need the latest features.

My Sony RX10iv spec. gives AF as a 300th of a second, I've never actually timed it myself.
