Zero evidence dude. There are dongles for USB C and SD cards.
USB C: audio, video, and charging all in one. Super thin ports. Apple goes backwards with an SD card slot and HDMI port.
Instead of Apple leading, they go backwards. The latest USB C data transfer speeds beats the breaks off of SD card data transfer speeds. And there are cameras that have USB C data transfer ports that can be used directly to a computer's USB C port, thereby negating the need for expensive, clumsy, and absurd SD cards. The camera industry needs to cater to the needs of these content creators and technology innovation, not technology companies like Apple going backwards in time.
This is all so boring and dumb.
