RalphsValve's insider Twitter account revealed that Activision plans to return to Call of Duty: Advanced Warfare and release a sequel to the story. Initially, the company wanted to develop Vanguard, however, after analyzing the low sales and critical reviews, it was decided to develop another sub-series.
True, we have to wait for new items, if it comes out, for a very long time. At least until 2025, as the project is still under consideration. It's too early to talk about the style, plot and other features, so we'll wait for the official announcement from the developers.
Well, yes - insider information should be taken with a certain amount of skepticism.
