Apple's long been a proponent of doing things wirelessly; the main problem is that both power and displays aren't yet wireless. I wouldn't mind if Apple came out with a new display or 'docking station', I think they would need only one cable to connect the screen + provide power. USB-C is really versatile like that.

A shame they got rid of the SD card slot though, and I will be very upset if they get rid of the 3.5mm as well.
