OKAY
I am officially calling this "first admit" a hoax!
After a thorough investigation (which involved actually registering an account with admission 411 site), there isn't a trace of anyone getting admitted yet!
In fact I was suspicious because if someone indeed get a call, I had to ask myself why I didn't get anything. (My ego talking - started when I scored 770 on GMAT

. with Magna Cum Laude undergrad degree + my good looks....who can say no to me??)
Fact #1 - Businessweek forum refers to someone reporting admit in stat page in Admission 411 forum. (Not actual post of person claiming to receive the call)
fact # 2 - Admission 411 forum for Northwestern has ZERO posts
Fact #3 - I turned the stat page on Admission 411 Northwestern page into PDF (which i attached here). Person won't reveal his/her forum name and easily that person could have said accepted for no reason whatsoever. Why would anyone update this one stat page and not update anything on forum/post etc???
fact #4 - Second person who posted that admit calls started claims to KNOW someone that did get the call.....That isn't reliable whatsoever.
