I don't know anyone specifically, but if you look at the website:
www.stern.nyu.edu click on prospective students and look for FAQ under applying and it states no deferment and you have to reapply.
If you look around the website there is a lot of good info. If you click on current students, instead of prospective you can see alot of info about classes etc without needing a password (you can go into sternlinks for part time and actually see sample class syllabi, etc.). It will be something to keep you guys busy while you are waiting to hear
I do know someone who was supposed to start with me last fall, but he couldn't make it to pre-term so they wouldn't let him in until the spring after he attended pre-term. I don't believe he had to reapply, but I don't know. He was none too happy about having to wait and wouldn't even discuss it.
