I can already tell you what the resolution will be for STILLS PHOTOS when Canon says the R5 can capture 8K video!
Unfortunately they don't tell you whether the video capture is DCI 8K (8192 by 4320 pixels) or UHDTV capture (7680 by 4320 pixels)
1) if it's DCI 8K then the STILL PHOTO CMOS sensor resolution WILL BE 8192x5455 or 44,687,360 total pixels (44.68 megapixels)
2) if it's UHDTV 8K then the STILL PHOTO CMOS sensor resolution WILL BE 7680x5120 or 39,321,600 total pixels (39.32 megapixels)
This means the camera CAN BE 44.68 megapixels (the most likely resolution!) OR it can be 39.32 megapixels.
This is because Canon ALWAYS does a 3:2 aspect ratio for it's still photo camera sensors AND since I HAPPEN TO KNOW A LOT OF MATH and that DCI 8K is ALWAYS 8192 by 4320, you can simply use 8192 as the starting base for calculating the VERTICAL RESOLUTION which SHOULD BE 8192x5455 pixels.
In many cases, it might be MORE because Canon has to normally ADD extra pixels outside of the sensing area for sensor calibration purposes, so it MIGHT be slightly more when it gets introduced. (i.e. but no more than 120 extra pixels on the horizontal and vertical)
