I haven't visited before and thought I'd contribute to the discussion here. I recieved my call from Michigan in the second week for February - at that time the DGS told me that those of us who'd been accepted had all been notified.
As for NYU - I got an email from a grad student friend who said it was good news for me and that all acceptances would be out in the next week - but who knows.
Good Luck all.....
