Most schools have probably chosen their first round of interviews by now, but maybe not all of them... and maybe not all have informed people yet.
What are your stats like? If they are decent, I wouldn't worry... if they are sub 3.3 GPA and 19 or less DAT in combination, then I'd more wait for later rounds of interviews and hope for the best. Don't start really worrying until somewhere between February and April. If you miss first round there are still plenty more to go.
Good luck.
