Ok well I'm almost certain that I heard the lady from the FAA tell congress we'd see the NPRM for comment by the end of March (when she was sitting in for Babbit on 4 Feb).
Of course we've gone from Jan to Mar already so who knows. Perhaps they're waiting on the scientific study for commuting and fatigue from the reauthorization bill.
EDIT: This is from page four of the hearing on 4 Feb.

Status of FAA Safety Initiatives Related to the FAA’s Call to Action
Fatigue: In July 2009, the FAA charted an ARC to develop recommendations for an FAA rule on
pilot flight and duty time. The ARC met its September 1, 2009, deadline and provided the FAA
with a broad framework for drafting a Notice of Proposed Rulemaking (NPRM) that the agency
planned to publish by December 31, 2009.
The FAA now plans to publish an NPRM in April 2010.
