The new edition should be available for Spring 2012 adoptions, and will contain significant updates reflective of important developments in antitrust law since 2003, including the 2010 Horizontal Merger Guidelines amongst other things. As the co-authors are also Washington DC-area antitrust profs, I’ve had the opportunity to get to know Andy, Bill and Jon over the past several years and am greatly looking forward to contributing to working with them on the textbook I’ve been using for years!
