This is what I know...I called Ms. Sheffler today.
Those who have the "tab" and the note (blah blah "strong interest in you and first considered off the waitlist) will most probably be accepted.
Those with the note but with no tab have less of an edge but are still in the preferred bracket.
Those without the note, i presume, are on the bottom half of the tier 1 waitlist.
I have yet to see anyone designated as Tier 2.
In my opinion, it is important to know how many "top of tier 1" people there are on the waitlist in order to get an idea of the chances of those ppl not on top. Since the FAQ section says that nearly 12-50 may get in, if there are a lot of Tier 1 ppl, then those of us not on top are prolly not getting in.
