This camera will most likely be in the same boat with someone upgrading from a 1Dx to the 1Dx mk2. If you dont do video with the camera you will be very disappointed.
Your pictures will most likely look identical in the same shooting situations at an equal ISO as they did with the previous version of the camera 3 or 4 years ago.
You will most likely get the F8 autofocus upgrade of the 1Dx mk2 and antiflicker but past that all you will see different in this camera will be slightly larger megapixel count and tons of video upgrades. If you only take pictures this will be an upgrade worth skipping.
