• The AF improvements are huge - from having a dedicated joystick for selecting the focus point to touch AF on the LCD to a noticeably faster and more capable AF tracking and a mind-blowing Eye-AF system(the camera locks onto your subject's eye).
• Battery life has more than doubled from the Sony a7R II. The Sony a7R III uses the new A9 battery the Sony NP-FZ100 which truly more than doubles battery life. I shot 1845 photos with the a7R III and 20 minutes of video - that used less than 50% of the battery!
• 10 FPS with mechanical shutter or electronic (Rolling shutter does make an appearance with moving objects in electronic mode)

• Sony listens - the AF improvements, battery life, fps and now DUAL CARD slots along with a host of additional features means Sony truly listens to the photography community and has provided a camera that nicely takes this mirrorless camera to a level that can replace your DSLR.
• The ergonomics and usability of this camera is much improved over the A7RII - it feels better in the hand and the placement of AF-on, the focus selector and the record button are all excellent
• The viewfinder is so bright and beautiful.

Bummers - No access to the play memories store - so timelapse fans will need to buy an intervalometer BUT with the additional USB-C port you can charge the camera while running longer time-lapses.

Image quality doesn't look drastically different from the already excellent a7R II but if you have been waiting for a Sony camera that can truly replace your DSLR or you are an a7r or a7ii shooter - this is an upgrade I can happily recommend.  I love answering your questions and will be back with more hands-on and answers to your questions in the next couple of weeks.
