And the Supreme Court's site says
"A cert petition is voted on at a session of the court called a conference. A conference is a private meeting of the nine Justices by themselves; the public and the Justices' clerks are excluded. If four Justices vote to grant the petition, the case proceeds to the briefing stage; otherwise, the case ends. Except in death penalty cases and other cases in which the Court orders briefing from the respondent, the respondent may, but is not required to, file a response to the cert petition."
So it looks like February 18, 2013 is the date for us to watch. (@sspats, et al, to Leah!)
"Generally, if a case is considered at a Conference, viewers can expect that the disposition of a case will be announced on an Orders List that will be released at 9:30 a.m. the following Monday."
