First, the obvious attraction: The new "transforming" D-pad. With a not-so-simple twist of the D-pad, the corner quadrants drop out of the way leaving just the cross-shaped D-pad. I say "not-so-simple" because it actually requires a little bit of effort; after all, you don't want to go from cross-shaped to old-fashioned in the middle of a hadouken. Using two thumbs to spin the D-pad improves the process though, when not being twisted deliberately, it remained firmly in place. We were told that engineering the transforming D-pad was no easy feat and the final product is not only the result of several prototypes, but all sorts of stress testing.
