My guess is we’ll get 10.6.1 since it is already out to employees, unless there is an issue with that.
But, we are coming close to holidays - so, who knows.
Optimistic :
10.6.1 : from tonight
10.7 : next week
10.8 : Dec-31
Likely :
10.6.1 : tomorrow
10.7 : Before Christmas
very prescient. 10.6.1 started releasing about an hour ago.
