Yep, my due date is July 31, 2013, one year after I got my AOR. It's a little strange that this is a function of AOR date and not application date.
I wouldn't be too discouraged if your file hasn't been looked at yet... GCMS is just a snapshot at one point in time and by the time you get the result, progress may have been made on your file. It's my understanding that once they do open your file, it takes little time to make a decision on your eligibility and send you a medical request if appropriate.
