Results from non-accelerator neutrino oscillation experiments have provided evidence for the oscillation of massive neutrinos. The subdominant oscillation, the coupling of the electron neutrino flavor to the third mass eigenstate, has not been measured yet. The size of this coupling U_{e3} and its corresponding mixing angle theta_{13} are critical for CP violation searches in the lepton sector and will define the future of accelerator neutrino physics. The current best limit on U_{e3} comes from the CHOOZ reactor neutrino disappearance experiment. In this talk we review proposals for future measurements of theta{13} with reactor antineutrinos.
