This is just according to a job listing on Treyarch’s website, which seems to specifically request someone with familiarity with modern day military hardware and weaponry. Now, I feel like it is best to point out that even if the game being developed were a ‘future warfare one’, it is likely Treyarch would prefer someone with experience with modern real day weapons, since their fictional weapons would be based on real ones to begin with.
So the job listing in and of itself doesn’t confirm anything- but it definitely seems to hint at something interesting nonetheless. Call of Duty: World War 2 is due this November on PS4, Xbox One, and PC by Sledgehammer; Treyarch’s game will release, presumably in November next year, and will be released early next year. We should know what it is about then.
