I'm thinkin' that those who have not heard back yet will hear soon, because the admissions committee is coming close to the end of their process - there likely will not be too much longer for any 'hold' category to remain, and all the 'holds' will turn into accepted/waitlisted/rejected.
My reasoning goes like this: If a person has been on hold for a long time, their application looks pretty good, and the committee might be wondering whether they should accept the person or waitlist them. Right about now, the committee has a much better picture of how many actual spots they have with which to accept more people. Likely, those that have been on hold for so long will now either be accepted or waitlisted. If they have been on hold for so long, they, perhaps, are looking quite good for the acceptance depending on spots available, the more recent folks interviewed, etc. Anyways - long waits translate into a good thing, according to my logic.
Furthermore, I'm interested in what sorts of acceptances happen this week, because I'm figuring that if many who have been on hold for a while get acceptances, that means that the 'hold' category was more like a traditional 'waitlist' category at places that waitlists move a lot. If the acceptances post-may 15th mean that the committee is looking at a more realistic picture of how many spots they actually have, that means that there would be less movement on a waitlist, because the acceptances that are made are more 'firm', less reliant on may 15th movement, and perhaps only reliant on whether folks get off waitlists, or get accepted elsewhere, and choose to go there. this late in the game, there is generally less movement like that, however, there is some.
o.k. i see what armydoc is saying - that more recent folks could be the ones who snap up the acceptances - the ones who would have done that anyways, and what is left is overwhelmingly waitlist spots. and, there may be more acceptance spots to give right now, post-may 15 which means that some of the long-waiting people on hold may find themselves with a final acceptance, rather than a waitlist. all of that decision-making post may 15 might mean very few spots for waitlistees right now. all up to how many people end up dropping an acceptance that they had confirmed at may 15.
so then the question turns to be - how many on the waitlist in the end, and what kind of prospect for there being open spots - good prospects, or slim prospects?
anyways - waitlist is better than rejection! each time, one step closer to the goal. MED will one day be mine, too!
