Imagine a next gen console with a headphone plug on the controller and having games give this type of sound experience. It would make those horror/suspense type games much scarier. Imagine a racing game, you are driving like mad and when you pass under an overpass you can hear the engine being reflected off the concrete or steel girders above, what the car would sound like roaring through a tunnel.

BTW, I have a sound card called an Aureal SQ2500 made 5 years ago that had this technology but hardly any games were made with it in mind so the feature was never used.
