I received an e-mail today that Action was taken on my case so, I logged into my uscis acct and saw the update:
on 12/11/18 Case has been sent to Dept of State for Visa Processing.
14 days from NOA2. Will begin to call in a couple of days for case number. Best of luck everyone, and if you have any updates on your cases please keep us up to date. Any info helps and eases the burden of waiting when there are signs of progress.. however little it may be!
