I was high waitlisted and told I should get pulled and didnt... only 3 people that year did, making it tough to get early accept that year too, which i didnt. it really depends on the class.
i was medium waitlisted at tucom for class of 2010 and got the early accept for class of 2011...my interview was only in april. anyways..if your high on the list..odds are u will get in this year or the next at least..keep them updated regularly and stay in touch with the office. good luck!
