Hogan, correct me if Im wrong, but I remember reading that the "any professional production" aspect was only for mountings in New York (can't recall if it was only Manhattan or all 5 boroughs). So, for instance, something performed professionally 8 years ago in Boston or Chicago could be deemed original by the Tonys. Unless they deem it a "classic" because its been part of the cannon for many years, in which case it goes into revival.
The rule is 3 years immediately proceeding the eligibility date and has not had a professional performance in the borough of Manhattan at any time in those three years. Unless I'm having a stroke, the last production in Manhattan was 2006, so it should be eligible for best revival (should there be enough candidates to warrant a revival award, which there will be).
