I was panicking in a similar situation until I was accepted (by email from a prof) to Illinois (Urbana-Champaign, obv) today.
My stats:
Good -
University of Illinois Urbana-Champaign - accepted, haven't asked about funding
University of Pittsburgh - attended interviews last weekend, will find out admission this weekend, haven't asked about funding (heard everyone gets stipends)
SUNY Buffalo - accepted via email BUT no funding (= not going there...)
Bad -
UPenn - rejected (woo)
MIT - nothing (all invites already sent out == implicit rejection)
CMU - nothing (their visiting weekend was last weekend == implicit rejection)
Rochester - nothing (sleuthing says their interview/visiting weekend is March 5-7 and invites have gone out == implicit rejection?)
Brown - nothing, but not expected to hear for a while
Stanford - nothing (== implicit rejection? unsure.)
A prof at Pittsburgh said that they had a BOX of applications from students who were well-qualified and should be interviewed but would not be due to higher competition this year. GAH. (Pittsburgh and Buffalo were supposed to be my safeties...) When I was visiting Pittsburgh EVERYONE (even those who were interviewing at CMU) had been rejected from Michigan. Yikes.
My uncle's on an adcom at BU and he is insisting that they have until the deadline specified to make decisions, so at least silence is better than being part of the immediately-rejected crowd. Small consolation. He also said that this is the time to contact the schools and pester (unless they say not to somewhere) so that you're not forgotten.
I don't know if this is what you were hoping to hear...
