Microsoft has been in and out of the PC gaming peripherals business with its Sidewinder family, and is heavily invested in gaming with the Xbox console and its ecosystem. The company is looking to expand the functionality of the console to bring more PC-like input to the console for certain game genres that cannot be played well with a gamepad or an Xbox controller. RTS games, for example, require rapid, high-precision pointing, and dozens of macros quickly accessible via a keyboard. Microsoft seems to have decided that it's time Xbox has proper keyboard+mouse input, and so it's collaborating with Razer to design new peripherals.

Microsoft already shared the implementation plans of bringing keyboard+mouse input to the Xbox platform, with game developers earlier this year, so they could either retrofit their released titles, or develop future titles with it (and work on ports of popular RTS games that are exclusive to the PC). This includes two new APIs for the console - "Windows.Input.Devices" and "Windows.UI.Core.CoreWindow," which brings a semblance of the UWP to the console. It also proposed new multi-player matchmaking rules to ensure players with keyboards+mice don't get into lobbies with players that have controllers, and end up with an advantage in genres such as FPS. Razer's Xbox peripherals could be both cost-effective keyboards and mice sold separately from each other; or contraptions such as the Razer Turret, which combine a keyboard, mouse, and mousepad into a single, living room-friendly, wireless device that you can put on your lap. Since UWP on the Xbox also paves the way for certain non-gaming apps, one can expect Razer to bring Synapse and Chroma to the platform.
