"Sorry for delay, I've had trouble logging into SCN. Yes, the second drop of the beta expired; we are required to end the beta before moving onto a delivery phase and can no longer offer overlapping periods of testing."
So they are in 'a delivery phase' but no hint was given about timeline for GA.
I mentioned awhile back on one of these posts that I thought we wouldn't get more than 7-10 days notice of the GA date. I still think that is the case.
