Rolling decisions?

<p>Two years ago, when my son applied, I seem to recall that he got his decision in October or November. </p>

<p>This year, my D applied EA. The website says EA decisions are released Jan 15. Is this new? Or is Jan 15 always the official date, with decisions released earlier, on a rolling basis, when ready? </p>

<p>My D's app was downloaded from commonapp on Oct 31.</p>
