Predicting your approval
vvvunlucky,
In line with the topic of this thread, I am taking a stab at the prediction. Looking at the movement in your case, and comparing with the pattern of others who have been getting approvals, you should see some positive movement in sep last week.
Having some movement (change in luds ...) indicates that some action is being taken about the case. That should be a good news.
So that indicates that USCIS is actively looking at the older cases, hopefully based on the PD though.
So, let us hope for the best.
