Blizzard "objects" to mouse and keyboard use on consoles for the competitive shooter Overwatch. When asked about the use of mouse and keyboard on the company's forums, game director Jeff Kaplan responded in no uncertain terms:The Overwatch team objects to the use of mouse and keyboard on console. For one thing, Sony does allow mouse and keyboard support easily for all players on the PS4. Will a console mouse and keyboard setup give you an advantage? Moving toward mouse and keyboard support, however slowly and painfully, is a good thing---for lots of genres, not just first-person shooters.
