DS still waiting here. Applied the very first day so it's been a long wait. Feeling like it's probably a no. My DS sent an email to admissions with some questions a month ago and it was completely ignored. I know they are busy, but it seems like a bad sign when they don't even bother answer.
Yes, things are very much on their time. I was accepted back in March to USNA SS, so right now I believe if everyone hasn't been accepted, they will send more acceptances as people decline. Or I would assume.
