First of all, there's no hard and fast rule, so I don't know how you feel comfortable making such a flat-out prediction. Also, to use your example, CRIPPLE was close to 20 years old when it came to Broadway and had two major NYC productions prior to Broadway. BLACKBIRD is around 10 years old and has only had one brief NYC production. I think, like Richard Greenberg's THE AMERICAN PLAN in 2009, it will be considered a new play.
