Closed Beta Update ? January 21, 2016 - Overwatch Forums
"After looking through all of the feedback from last year, one of the things we noticed players consistently mentioning was their desire for more game modes in Overwatch, in addition to Point Capture and Payload. Without getting into specifics, we are working on a new game mode. And we’re very excited about it! And we have some great new maps to support it, too, but we need a little more time to get everything just right."
"we’re going to take a few extra weeks before bringing the Closed Beta back. By doing so, we can make sure we can include the new game mode along with the new maps."
"I don’t have an exact date for when the Closed Beta will resume, but right now we’re looking at mid-February (and we don’t intend to slip out of February)."
We now have a concrete-ish timeline!
