A particular Fermi-point-splitting (FPS) model is proposed, which allows, for finite values of the three-momentum, the group and phase velocities of the muon-flavor neutrino in vacuum to be superluminal (i.e., muon-neutrino velocities greater than c, the velocity of light in vacuum). Still, the proposed FPS model has a front velocity equal to c for all particles, which is known to be crucial for causality. If the muon-neutrino velocity is indeed superluminal as claimed by OPERA, the model predicts that at least one of the other two flavors of neutrinos has a subluminal velocity.
