We know that Call of Duty: Black Ops 4 is going to happen but at this point, there is not a whole lot of information about the game at all. However, new reports are suggesting that Call of Duty is ready to change based on what the consumers enjoy right now.
With games like PUBG and Fortnite dominating right now, and it is clear that Activision is aware of that as well. According to Oppenheimer, Activision is well aware of the popularity of Battle Royale genre games and the management suggested that Activision is a fast follower.
While that is far from a confirmation, it does suggest that we might see a Battle Royale mode when the new Call of Duty: Black Ops 4 arrives although we might see Activision out their own twist to it. The new Call of Duty: Black Ops 4 will be arriving on the 12th of October this year on PC, PlayStation 4 and Xbox One.
