While it mostly looks the same, the Xbox One controller has undergone a few changes.
Marc Whitten, the General Manager of Xbox Live, revealed that the controller includes improved ergonomics, an integrated battery compartment, “Impulse Triggers to build feedback directly into the controller,” Wi-Fi Direct Radio Stack, and a Precision Directional Pad.
At least it still includes four triggers, four face buttons, two analog sticks, and a D-Pad.
