Finally Atlanta is moving again! Got my text/email on December 11th that I have been scheduled for interview. I don't have the letter yet (I'm out of town actually but my better half will give me the date when the letter comes). Several others on Trackitt who applied around the same time as me, also got notices on the 11th. I filed 6/29, priority date 7/2, fingerprints on 7/26 and in line for interview since 7/30. I expect the interview date will be in mid January - I'll update when I have the exact date.
