The Jackson case has been relisted for conference on Friday, March 18, 2011. Philip Morris USA, Inc. v. Jackson, no. 10-735. Unless the case is relisted again, the vote will be announced on the following Monday, March 21.
This is what SCOTUSblog has to say about relisting:
If a case has been relisted once, it generally means that the Court is paying close attention to the case, and the chances of a grant are higher than for an average case. But once a case has been relisted more than twice, it is generally no longer a likely candidate for plenary review, and is more likely to result in a summary reversal or a dissent from the denial of cert.
