We just got approved! After 9 months and 5 days of waiting. NOA 1 - Dec 11th; NOA 2 - Sep 16th.
I do, however, want to say that a little miracle happened. I contacted USCIS live agent via Emma chat this morning. They told me that I, as a beneficiary, am not authorized to discuss the case; only the petitioner.
My finance then made the call, and has been told that they have no other available info to give him, other than what's on the official website.
Approx. an hour later, our case was approved. It could just be a coincidence, but the timing is incredible.
