With Patch 10.1.7 a little more than a week away, Patch 10.2 may hit the PTR soon with the 10.2 patch now an encrypted Vendor Build!
While this is encrypted, and not able to be datamined, this may indicate that Blizzard is ready to push Patch 10.2 to the PTR shortly before or after Patch 10.1.7 Fury Incarnate goes live on the 5th of September.
