This year's Call of Duty game is Call of Duty: Black Ops 4, multiple sources have confirmed to Eurogamer.
Black Ops 4 is in development at Treyarch, the Activision studio behind the three other Black Ops games, and as you'd expect is due for launch late in the year.
Word of Black Ops 4 first appeared online this week in a Twitter post from self-styled "industry insider" Marcus Sellars. In a series of posts made over the past few days, Sellars also referenced a Nintendo Switch version of Black Ops 4 was in development - a detail we're still working to verify.
