Xbox spokesperson Major Nelson officially unveiled the rumored new controller design. Changes appear to be light as aesthetically the controller retains its comfortable shape. However, there are some significant enhancements to the input aspects.
The abhorred original d-pad has been modified to lift up and down slightly by doing adjustments with a simple twist and appears to give an overall better control input. The sticks have also been enhanced slightly as well as new coloring for the buttons.
More info will be available during PAX.
