Gamemanx.com posted a brief hands on with the Mad Catz SF4 joystick, which has a rather... interesting video.The most notable thing about the joystick itself was the slant. The area where you would rest your wrist is slanted downward making the joystick more comfortable and ergonomic. It's noticeable right off the bat and is a great design choice.
The joystick had recessed start and select buttons on the back and the art on the joystick was good I guess but nothing to flip out about though who knows that may change as the joystick could have been a prototype so much could be subject to change. The slanted front design alone makes this Street Fighter IV Joystick one to watch.
