Not what I expected as news:
Microsoft has leaked word of a new Xbox One controller, presumably to be revealed next month at E3.
The company's own Xbox Support website has been updated with mention of a 3.5mm headphone port at the base of the pad.
This new feature is "only available on controllers released after June 2015".
What other new features the pad will offer is unknown.
One frequent request from Xbox One owners is for a controller that can be charged via USB cable straight out of the box, rather than via a Play and Charge kit (sold separately).
But the fact that the design is otherwise identical suggests that the overall form factor of the controller will remain intact.
