  Radiative penguin decays provide a hunting ground complementary to direct
searches for physics beyond the Standard Model. In the era of B-factories
copious production of B mesons permits precision measurements of radiative
penguin decays. We present herein the status of radiative penguin processes and
expectations at high luminosities, focusing on b -> s (d) gamma, b -> s l+ l-,
and b -> s \nu \nu bar modes
