I'm in the same boat as you... their classes start on Sep. 10th, so i'm assuming we should hear for sure in the next couple of weeks. Although i do have a sneeking suspicion that they simply forgot about us.
I was in the same boat (waiting on 3 schools) and e-mailed ABP about 2 weeks ago to get on their radar screen, was offered a place Aug 17 for Sept 10. My advice would be to write quick e-mail, have had great service from them.
