Here's a few that have come to my attention; some transpired a few months back, though I learned of them (or had them confirmed) more recently:
Ann Bartow (intellectual property, cyberlaw) from the University of South Carolina to Pace University.
Kenworthy Bilz (criminal law, evidence, law & psychology) from Northwestern University to the University of Illinois, Urbana-Champaign.
Gabriel (Jack) Chin (criminal law, immigration law, race and the law) from the University of Arizona to the University of California at Davis.
Adam Cox (voting rights, immigration law), from University of Chicago to New York University (where, alas, his wife had a professional opportunity unavailable in Chicago).
Paul Heald (intellectual property), from University of Georgia to University of Illinois, Urbana-Champaign.
Vicki Jackson (comparative constitutional law, federal courts), from Georgetown University to Harvard University.
Kristin Madison (health law, economics & policy), from University of Pennsylvania to Northeastern University.
Tanina Rostain (legal ethics) from New York Law School to Georgetown University.
