Activision thus far has not announced an end date to the beta, only announcing the start date for each platform.
The Blackout Beta is set to officially begin on September 10 on PlayStation 4, with Xbox One and PC start to follow on September 14. The Blackout Beta requires a pre-order in order to get access on consoles, while the PC Beta will be an open beta starting September 15.
If the September 17 end date is true, PS4 players will get a whole week of the Blackout Beta, while Xbox One and PC will have 4 days for the beta.
We’ll update as we learn more.
