The only other change is that the new PS4 controller features USB communication. Unlike the original DS4, it means you’ll be able to play games either wirelessly or via a USB cable.

Huh? I was able to use the original Dualshock 4 on my PC via USB connection since day 1.

That's what I sort of figured.
