did you read the article on Murthy.com abt PD retrogressing??
The article says that the priority dates are possibly not going to retrogress until the mid of 2003. So don't have to worry.
Another thing to note as far as processing times are concerned os that, there were lot of cases filed in the month of July,Aug & September. After these months passed, INS didn't receive that many cases ..which means the processing is going to be much faster than it is now. So there is a possibility of a lesser wait time for people having filed after September(During Sept 11- 30 there wasn't much activity at INS also). Currently VSC is the fastest but who knows, it might become the slowest because we have seen this happening in the past.
What I would recommend is to sit and relax and wait till they start handling 2002 cases. Thats when we will know where you stand. And as WhoCares1 rightly said..Patience is virtue.
And please don't keep on calling IIO when your receipt date is of future. This might just push back the processing times and also hold back your case looking at the no. of calls you make to know the status.
Hope my post did make some sense.
