I care a lot more about the prism, focus point/speed and image quality.
It depends on the WiFi implementation. 802.11ac is plenty fast and could theoretically open up a crazy amount of possibilities if manufacturers opened up their code and enough people wrote code for it. You would be able to send data fast enough to a nearby computer and take advantage of the latest AI image processing and machine learning, then communicate all of that back to the camera to control it. Near perfect AF tracking, exposure, white balance, image stacking, etc.
