I think there is still some room for hope if you haven't heard back yet. Based on the info I dug from the boards over the past few years NYU DW does not seem to notify rejections last (as other programs do). Although the sample size from the boards is small, it seems in prior years that notifications have generally gone out in the following order: rejections (staggered), then waitlist (all at once), then acceptances (all at once). However, this year, Rohan received acceptance after the initial waves noted above. So they could very well be still considering candidates. Why not just reject a candidate if you're sure they won't be there in the Fall?
Also, I could be wrong, but I think this was the first year NY applicants had the option to indicate on their application that they would like to be considered for Asia. I speculate this added a wrinkle could be causing some delays.
NYU has sent out a note to at least some accepted DW candidates about a meet and greet next week, but there's no reason to think that this precludes them from inviting more people if/when there are additional accepted candidates.
