That Sony announcement was for Japanese market, indicating that there's not enough volume to meet all the received pre-orders from the first shipment (for Japan) on 11/25 (Japan release date) so the orders will continue to be fulfilled in order they arrived past original release date.
Same could happen elsewhere too but the announcement was for Japan market only.
Well that helps but the pre-order situation still stands. Its very hard to distribute evenly and accurately to the small, medium, large size stores when the count is really not correct.

Yeah, I just wanted to clarify the announcement that SAR referred to. I agree that U.S. order/stock situation is another challenge due to people pre-ordering from multiple sources. That doesn't happen in Japan in general.

Thanks, but what does “but better in every way” mean? Better than the A99II or better than the A7rII? And what do you mean by “other than -EV performance”? That it cant AF in the same low light as the A99II?
Better than both cameras. The edge for the a99II will be lowlight performance i.e. -4EV.

And given the SLT mirror AF provides way larger PDAF points vs. sensor-based I would expect A99II to provide decent tracking to lower light levels. Hybrid AF in E Mount cameras is mostly CDAF as light levels go really low.

Well, I'm not pre-ordering, not earning enough and a car that it is giving too much headaches... but I will be looking for your A7r II second hand (for those of you that are in Europe)...

Thanks, that sounds excellent! I really got the envy when the A99II come out, and now the A7r2 is giving me that sad dog look again ...
The R3 is so much more responsive than any camera other than the a9.
There are a lot of attractive deals on used MkII cameras, but they are turtles compared to the a7RIII and a9.
The joystick also works well, much better than the a99II.

But the increased CDAF points and inrpoved processing capabilities in the mkIII should improve low light tracking.

Yes and propably do, but CDAF by nature (sampling by "trial and error") is not as efficient for tracking as PDAF which effectively gives distance metering. Also, SLT based system is never "blind" whereas any sensor focusing system is when there mechanical shutter is closed and SLT-based tracking propably operates wide open, unlike E Mount camera which stops down after initial focus lock in AF-C.
Don't take me as a hater, I've never owned SLT camera and never will; just saying that there are real advantages in them that are not available in E Mount cameras like the A7R III I have preordered.

True but the speed of that sampling has improved significantly as the processing capabilities of the camera improve...there used to be very visible hunting a few years back, and now the sampling is basically imperceptible. Since its a software based system, Moore's law comes into play.
I actually had an a99II loaner a few weeks back for a wedding after I sold my a9. Low light af acquisition was certainly faster than the a7rii I was using as a second body BUT the tracking would get tripped up more easily because the off sensor pdaf system it prioritizes does not have the density as on sensor systems. This surprised me since the a99II has an on sensor pdaf system but the off sensor system kicks in first and it would jump off the target unexpectedly at times. It behaves more like a DSLR in that regard, and not like the a7 bodies which I keep in af-c pretty much exclusively.
Also not knocking slt's, but this was my observation.

CDAF sampling is limited by many things, not just processing though more processing horsepower obviously helps. Sensor readout speed limits sensible sample rate (A9 has 60 updates per sec, due to way faster readout speed), sensor noise characteristics limit how low light it will operate in (original A7S with ancient processing was -4 EV). Focus motors are one thing, there has been progress in linear focus motors, use of multiple motors the get better sample rate. Also, we have no way of knowing when sensor-PDAF is or is not in play.
The future obviously belongs sensor focus but there still is ways to go before it is one tech to rule them all.

The A7rIII's read noise reduction is very impressive. Besides the improvement at base ISO, its performance at Ultra High ISO's now matches the A7s (when normalized to the same resolution). Here's a link I generated using dpreview's widget:

dpreview's widget shows A7Riii's IQ is a great step up through out whole iso range in all lighting conditions compared to most tested models out there. Can't wait to see more tweaks in production body.

Since Noise Reduction is applied above ISO 25600 you may (are probably) attributing something to read noise improvement that is actually a noise reduction improvement.

I purposely chose an ISO at the NR cutoff point. Here's ISO 25,600 just below it:
