If this is truly the prototype, then the design will change a little bit for the actual product just to make it more stylish. What I like from looking at is the D-Pad. It's the same as the Vita and you know that D-Pad is the best so far, I constantly play my fighting games with it. The touch screen on the controller is a nice addition.
