25 minutes/4gb for 4K (?). I can live with that if it's 4K....and I think it's not cropped 4K? Would be fine for all of my purposes at this time (I don't do interviews....) Heat is the devil, so I can forgive a camera about heating up, especially in hot weather. Mitigating that has been a challenge for all the manufacturers.

In another thread, @angerdan posted a link to the owner's manual:

Astrotracer is supported but requires the O-GPS1 module.

The ambassador video below from a Korean studio portrait photographer (around the 2:50 minute mark) talks about high speed tethering over USB 3.

Depth of field bracketing! Motion bracketing? What does that mean?

DoF bracketing: Automatically shoot a burst at multiple apertures so that you can decide in post which has the DoF you desire.

Motion bracketing: Automatically shoot a burst at multiple shutter speeds so that you can decide in post which best freezes/blurs motion.

I-R says it's 25 minutes regardless of video format, or overheating, whichever comes first.

Yeah, that is it for other cameras too. What info is lacking is bitrates. I'v seen just small clips, but looks already better than full HD. So bitrates are better than before.

USB-C charging and supply is a very nice feature too. More options for charging in the field and I expect will be much better tethering. Not to mention maximum 12 FPS - this is a rocket ship (for mirrored anyway)!

Its looking a pretty desirable feature set, although missing out on Tilt screen, GPS and Flash (personally I can live without onboard GPS and Flash but I must admit, much to my own surprise, I have grown pretty attached to the K-1s tilt screen).

Thank you.
The Face detection and eye/pupil-AF as well as bird/animal-detection and tracking during PDAF isn't included in the current version of the complete specs.
How will they be mentioned?

And how about the possibility to charge the battery inside the camera via USB-C ?

I am surprised to see Electronic shutter missing as a live view option. Perhaps as a firmware feature, eh?

I was hoping to see in the user guide, whether the Bluetooth could be used to get GPS coordinates from a smartphone, but it only says to refer to the wireless communication guide for details of connectivity, so will need to go looking for that.

That one is very cool, though I still think Ricoh/Pentax should have bundled the USB-C charger with the camera at this price point.

*-4 EV is only available for AF points that support F2.8 light flux when an F2.8-light-flux compatible lens is attached.
Can someone explain this to me?

The preliminary Operating Manual (linked by @angerdan), English version, page 36, shows:

Setup Menu page 4 > Smartphone Link > Store Location Info (ON/OFF)
Records the location information of the communication device in captured images.
