Is The Next Call Of Duty Game Black Ops 4

The rumor came from Marcus Sellars and as well as saying it would be Black Ops 4 he also said that it would be set in modern times and be a “boots on the ground” kind of game. By that, I take it to mean that there will not be any futuristic stuff like we have seen in some of the past COD games and that they will be sticking to the more realistic approach that Call Of Duty WW2 had.
