Microsoft first introduced its Xbox Elite Wireless Controller back at E3 2015. The $149 controller has four interchangeable paddles around the back, Hair Trigger Locks, remappable buttons, and completely swappable components. It’s been a popular choice for Xbox One gamers, and even PC players who occasionally want to use a controller, and now it looks like a second version is on the way.

Several images have been posted on Chinese site Baidu that appear to show a second version of the Xbox Elite controller. An anonymous poster claims the new version will include a USB-C port for charging, Bluetooth support for Windows 10, three-level Hair Trigger Locks, longer key travel for the paddles, and a three-profile switch.
