In Call of Duty: Warzone and Modern Warfare, players are waiting for the start of Season 4, which was originally set to begin on June 3. Now there are indications that it will take place on Wednesday, June 10. The release time is also known.
Update 13:17, 10.6.: The dataminer’s finding has turned out to be incorrect. On the morning of June 10, Season 4 did not start. At the moment, there is no start date for Season 4 in CoD Modern Warfare and Warzone.
Activision’s support only states that there is still no start date for Season 4, but players should keep an eye on the official channels.
However, it likely won’t take too long before Season 4 starts.
Original report:
When does Season 4 start? The recently found release date for Season 4 is Wednesday, June 10, at 8 AM our time. That is exactly one week after the original release date of June 3, 2020.
The start of the season has been postponed indefinitely to allow for more coverage of the “Black Lives Matter” movement in the USA.
Where the information comes from: The dataminer “TheMW2Ghost” found a file in the data indicating this release date.
Other dataminers have confirmed this finding: The date for Season 4 actually appears in the files, it is reported. This has been confirmed by multiple sources.
Call of Duty will likely wait for developments in the USA
How likely is it that it will start then? It is understandable even without datamining that Wednesday, June 10, is the logical start for Season 4.
Because the start of the season was not delayed due to technical reasons or because something was wrong with the build, but out of respect for the current situation in the USA. Therefore, it is likely that Activision Blizzard wants to maintain the normal update cycle and schedule, just shifted by a week.
Nevertheless, the start is not certain, as there is currently a dynamic situation in the USA that could escalate further at any time. If the unrest in the cities continues to escalate, it is quite possible that the start of Season 4 will be postponed once again.
In some parts of the USA, there have been civil-war-like conditions in recent days. A contentious issue is that police are using surplus military equipment. Therefore, a military shooter like Call of Duty: Modern Warfare is in a difficult situation.
To give the “Black Lives Matter” movement more space, the important reveal event for the PS5 was postponed, and Fortnite has also put all plans for new content on hold. At the moment, some gaming companies are stating that it is not the “right time” to talk about games.
