Call Of Duty games always leak early. Whilst they’re not the hardest games to predict (as they usually follow a pretty set routine), they usually leak early, whether this be a controlled leak (which it looks to be in this case) or just by industry insiders.
Whilst it was rumoured that Treyarch would be going back to Black Ops for this year’s iteration. It’s pretty much confirmed at this point (unless Activision as really trying to throw us off the scent).
Fast forward to today, in an even more bizarre situation, NBA Superstar, James Harden appeared in what looked like the Call Of Duty: Black Ops 3 logo, but with an extra stroke (indicating that its likely to be Black Ops IIII).
