Official Rejection vs. Not hearing anything

[soc_leah]

I'm wondering about my chances at a few schools that I know have already sent out their "first round" of admissions, (mine not being one of them).

Specifically, Harvard, Berkeley, and U of Chicago have all accepted people. Has anyone been officially rejected? If not, should I take my non-acceptance as early rejection? I realize it's not over until the fat lady sings, and even if one is rejected by a school, they can go ahead and rescind this if they want and accept you--this happened to my brother-- but overall, what do you think my chances are here?
