Here is a side by side image between the Panasonic S1R and Sony A7rIII via Dpreview:

The camera is big and expensive. It’s more “DSLR styled” than the competition. Panasonic might decided to go for a certain niche of photographers that want the DSLR feeling and handling. I am curious to learn if those cameras will sell well!

At 2/100 sec evaluation speed for Continuous Autofocus, the Sony a6400 has the fastest responding autofocus currently on the market. It shoots ten frames per second, with the new AI Tracking. However, getting to the tracking is quite an ordeal, which I will explain here. First if looks for the eye-ball, then the face, then the object or person. And coming soon – ANIMAL EYE-AF. The a6400, at under $900 is an amazing deal. To really learn how to use it, SUBSCRIBE to get the first announcement on our a6400 premium, “unleash the power of your Sony a-6400” coming soon. Also, tired of the searching through the menu bars trying to find that function? Our mobile, “Feature Finder” app will soon be available for the a6400 so you can find your menu item quickly in a sea of over 200 commands.

Sony A6400 preorders:
USA at BHphoto, Adorama, FocusCamera, Buydig, Amazon.
Europe at Calumet Germany, ParkCameras UK, Jessops.
Asia at Sony Australia and Sony Japan.

Some more praise from well-known reviewers:

Tony made this freeze resistance test with the newly announced Olympus E-M1X and the Sony A7III. Sony isn’t doing the best weather sealed cameras yet. But Sony managers already officially stated that future cameras will be much better in this regard!

DpreviewTV just posted their Sony a6400 first impressions video:

What I like most of this video is his conclusion where he says don’t buy the A6500…wait for the replacement!
I don’t think he got some insider info…I believe it’s just his guts telling us that we should wait for Sony to finally give us this A6500 successor.
