Nuby is working closely with Capcom these days. One example of this is their collectible Street Fighter Controllers. These controllers have a 6-button layout and look to be quite ergonomic. They sport some really cool Street Fighter character graphics on them. In fact, it's not just a single picture, but a 3 frame animation that 'moves' when you tilt the controller.
Each model is available at a different retailer. Additionally, there will be a metalic special limited edition of the controllers with a wooden box. These will be individually signed by the artists and will be available only thru Capcom.
Stay tuned - we're hoping to be giving some of these Street Fighter Controllers away in a contest!
