We update our study of neutrino mass hierarchy determination using a high
statistics reactor electron anti-neutrino experiment in the light of the recent
evidences of a relatively large non-zero value of \theta_{13} from the Daya Bay
and RENO experiments. We find that there are noticeable modifications in the
results, which allow a relaxation in the detector's characteristics, such as
the energy resolution and exposure, required to obtain a significant
sensitivity to, or to determine, the neutrino mass hierarchy in such a reactor
experiment.Comment: 7 pages, 1 figure, to be published in Journal of High Energy Physics
