Microsoft is releasing a new controller for the Xbox 360 in a couple of months. This controller has a strange new feature in the directional pad. The d-pad can be rotated to allow for different control schemes that uses the pad. According to a Yahoo article, this is supposed to present an advantage in fighting games. There are some pictures of the d-pad in both positions on the official page for the controller.
On the down side, this controller is going to cost $65 US. That's easily equal to the price of an average game. I'm not sure how many of them Microsoft can reasonable expect to sell at that price point.
What do you think of the idea of controllers with configurable parts like this? Are there other buttons that you'd like to see made configurable?
