The Overwatch Beta has been declared finished for 2015. There will be no new invitations.
The Longest Server Maintenance in the World
No one probably expected this. The closed beta of Overwatch will go into hibernation on December 10, 2015. The servers will be shut down and will not be activated again until late January of the following year.
According to Blizzard, more than 900,000 games have been played in recent weeks, providing developers with a wealth of data. Community feedback has also been acknowledged, and work is actively being done on various features, such as a spectator mode or a progression system.
Anyone hoping for beta access in the last few days can send that hope into hibernation as well, as the next invitations will only be sent out with the resumption of the beta next year.
Overwatch will be released next year, both for PC and for the consoles Xbox One and Playstation 4. Contrary to all assumptions, it is a full-price title and not a free-to-play game.
