Neutrino mixing: Theoretical overview

We present a concise review of the recent important experimental developments on neutrino mixing (hints for sterile neutrinos, large θ13, possible nonmaximal θ23, approaching sensitivity on δCP ) and their implications on models of neutrino mixing. The new data disfavour many models but the surviving ones still span a wide range going from Anarchy (no structure, no symmetry in the lepton sector) to a maximum of symmetry, as for the models based on discrete non-abelian flavour groups that can be improved following the indications from the data
