I have still not heard back yet. But I'm not really worried. The last piece of my application (official transcripts) were sent out last monday. I still have a few weeks of anxious waiting to do.
If you sent your application out early and still have not heard back, there's really no guessing your decision. Whats certain is that you are most likely a middle case. Not the strongest but most certainly not the weakest. With these cases they end up holding out their decision for a few more weeks. The admissions offcers generally would like to see more applications before they decide your fate. This is neither good nor bad. It just is what it is
