What is the origin of the observed fermion masses and mixing parameters? Neutrinos, with their small mass and large mixing, contribute an important part of this flavour puzzle. We discuss new developments regarding the flavour puzzle in the light of the recent discovery of comparatively large leptonic mixing theta_13. The new developments include the possibility to explain the observed value of theta_13 from charged lepton corrections in Grand Unified Theories, a new type of Constrained Sequential Dominance models leading to tri-maximal mixing with predicted theta_13 and unsuppressed CP asymmetries for leptogenesis, as well as a new class of models with predicted CP violation in the quark and lepton sectors.
