The USPTO website shows that Activision Blizzard has filed a Trademark application for Overwatch for the following services: "Computer game software, computer game discs, downloadable computer game programs, computer game software downloadable from a global computer network, electronic games software for wireless devices, interactive multimedia computer game programs, mousepads, computer mouses, headsets for use with computers, computer keyboards." Worryingly, the initial application is dated April 1st, but there is an additional update about this from yesterday, and Blizzard is never shy about publicizing their April Fools' jokes.
