Capcom and Madcatz are working on something very limited at the moment. From the teaser image posted on their blog it looks to be another killer iteration on their Street Fighter themed joysticks. The ring on the joystick is embossed with the all the directional moves for SF's special attacks and the buttons could be color coded from heavy to light attacks. At least Capcom is being forward on them being crazy limited, so they will be even more rare than the already rare SF4 fighting sticks. More information should be coming around later this month.
