The coming of Season 4 will affect not only Modern Warfare, but also Call of Duty: Warzone, a cool battle mode. This probably explains why fans of CoD on PC, PS4 and Xbox One are already wondering when the next big update is due.
At the time of writing, no official Modern Warfare season 4 release date has been announced, although based on the previous release, we can make a reasonable guess when it will be.
Start date for the 4th season of Modern Warfare and Warzone
Wednesday, June 3, 2020.
We know that season 3 is currently scheduled to end on Tuesday, June 2, and that the new CoD: MW season usually starts 24 hours after the previous one. Infinity Ward usually releases updates at 18:00 UTC, which makes it the most likely time to start season 4.
This gives players eight weeks to enjoy season 3 and try to maximize their fighting passes before the cycle starts again, which is possible with the launch of season 4 of Call of Duty: Modern Warfare on Wednesday, June 3 at 18:00 UTC.
Since the seasons traditionally tend to last eight weeks, we can expect the 4th season of Modern Warfare to continue until the end of July.
