For R2 applicants who still haven't heard a peep from Stern: there's hope. I got an email from adcom yesterday requesting additional information (a pretty peripheral piece of information, I might add). The timing and tone of the email suggested that they had just read my application for the first time. I applied on 1/6.
I'm a few weeks away from a deposit deadline at another school, so getting an interview invite at this stage (assuming that's the next step) will mean that I'll be cutting it pretty close. Not that I'm complaining - I'd take an invite / admit no matter where I was in the process!
