Broadway these days

So Broadway's changed, we all know that.  Its mostly blockbuster musicals for the tourists or star vehicles or the tried and true.  But here's something, and I don't know if there is any meaning to this.  I happen to know two relatively young directors, new to broadway, Pam MacKinnon has just opened her second production and Sam Gold is soon to make his debut.  The plays?  Who's Afraid of Virginia Woolf and Picnic respectively.  Woolf is having its forth go around (1964, '76, '05 and now) and Picnic its third (1953, '94, and coming in 2013).  What's the headline?  New American Writers Left For Dead?  Up-and-Commers Cut Teeth on Old Leather? Producers Hold Cards Close To Vest, Just In Front Of Pacemakers? Or is it just Broadway these days?
