I'm just a casual observer so I'm probably way off, so grain of salt but, I believe we'll see more prizes get awarded more quickly as the people who initially lay out the theoretical physics and design the experiments to test their hypothesis are no longer living long enough to see the results of their experiments because the technology to test their ideas lags so far behind what would be needed. Just think of Higgs and the fact that the LHC had to be planned, funded, built, and then used to confirm the Higgs-Boson. Same deal with LIGO.
