Assuming no future major influx of fresh gas, we estimate that these gaseous DSFGs will deplete their gas reservoirs in ~300 Myr, becoming the massive quiescent ellipticals dominating cluster cores by z ~ 3. Using various methodologies, we derive a total z = 4 halo mass of ~1014 M ⊙ and estimate that the DRC will evolve to become an ultramassive cluster core of mass 1015 M ⊙ by z = 0.",
