The biggest changes were replacing analog sticks with circular touchpads and plopping a small touchscreen into the middle of the controller. Valve has now revamped their prototype hardware, and the touchscreen is nowhere to be seen. In its place are stop/play buttons (which appear similar to start/select buttons) and a bigger Steam logo button. They've also moved around the directional and ABXY buttons, reverting to a more traditional layout (picture). They'll be demonstrating the latest prototype next week at GDC.
