When can I expect to hear back from a wait-listing?

<p>I applied Early Action to the University of Michigan and got a dreadful response of being wait-listed. Many of you know the pain-staking wait for an answer. They told me that the latest I would hear back would be mid-April, which is a long ways away in my book. Do you think that that is when they let all other Regular decision application decisions are released or will they probably let me know before most other applications are reviewed?</p>
