Activision Blizzard has already told that it wants to pay special attention to Call of Duty: Black Ops 4 on the PC. While the reasons for this love are not known, but there is a rumor that Black Ops 4 will be the exclusive Battle.net on the boyar platform.
What is known
Gaming Journalists Intel said they received information from a source that used to give correct predictions about Black Ops 4. Anonymous showed pictures of the internal client Battle.net, which is used for quality control. In the photo you can see that under the icon Destiny 2 there was a logo of the new "witch".
According to the source, Activision Blizzard spends a lot of effort on the PC-version of the game, to make the transition to a new client painless. It's unlikely that fans will stop playing CoD, just because of a new client, but thanks for caring. Last year Blizzard said that they let Destiny 2 on its platform as an exception. This can be considered as a fact that refutes rumors, but on the official CoD website since March there is an entry through Battle.net.
The second rumor is even steeper - in Black Ops 4 will appear the mode of the royal battle. Apparently, the success of Fortnite and PUBG does not give rest to other developers. In April, at once three gaming sites - Polygon, Charlie Intel and Kotaku, - confirmed the development of this mode. Treyarch scored on the storyline campaign due to lack of time, but concentrated on the diversity of multiplayer modes.
