Looks like the Canon EOS 5D Mark IV(4) will be announced in October  along with a new pro printer.
It is going to shoot about 12 FPS and be about 28 MP with the new digic VI(6) system. It is also rumored as having Dual Pixel AF III, advanced AF technology, anti-flicker technology, crop mode, and an ISO range of 100-204800.
Dual Pixel AF III: 61 cross points and auto focus assist light
All Canon EOS EF lenses should work. Including older lenses from as far back as the 1980s.
Old manual focus FD lenses or earlier won’t work.
What I would like to see in this new digital camera:
Easy to use hue/color adjustment settings.
Lots of fun filters: Miniature, pop colors, toy camera, etc. Also the ability to make and load our own.
USB Type C
Wifi and GPS built in
Wireless charging from their new dock
