Hubris is just over the top rhetoric. I've since researched further and found the following...

Progress towards Gravitational Wave Astronomy
Maria Alessandra Papa
Max Planck Institute for Gravitational Physics
"In two years the enhanced detectors will have increased the volume of Universe that we
can see by a factor of 8. In six years this volume will have increased by a factor of
1000. At that point cherished beliefs will have to be questioned if the data do not reveal
any gravitational wave signal.'

About a year old and it didn't factor in the recent increase in sensitivity cited in the 1st article, but it is premature at this time to declare grav waves as missing although the lack of detecting any events whatsoever over LIGOs 1st 3 (now going on 4) years was unanticipated.
