Of course it does. but just as Planck showed there were some statistical 
rules with EM radiation and then Einstein showed the so-called Einstein 
coefficients with the statistics of photons, the same should hold for 
gravitational radiation. There should be some statistical properties 
underlying gravitational waves that betrays some quantum mechanical 
undercarriage to  GR.
