In other words, the Xbox One will eventually play nice with a USB mouse for the simple fact that the console itself already sports keyboard support at the moment. While just a handful of companies such as Xim4 have rolled out adapters for systems such as the PlayStation 4 to let one enjoy a keyboard-and-mouse combo, Microsoft will be taking a different route, as they target the inclusion of official support.
How soon will the masses then be able to see official mouse support on the Xbox One? Taking into consideration how the Xbox One runs on an update schedule that will obtain a patch approximately one time each month, then chances are we could be looking at something more concrete before the year is over.
