LHC may or may not find the Higgs boson. We need to start thinking seriously about the situation when Higgs does not exist. The long contemplated model:Technicolor model or its extension is an alternative but it has few predictions and practically no understanding of flavor physics is provided in this model. Here I want to present a model in which not only the fermion pairs but scalar and scalar pairs have vacuum value. The result gives a S(3) model with its breaking by phases which we showed some time ago to be consistent with the current flavor physics. Precision EW tests would be the same as in the case of ordinary technicolor model. The work is still in progress but seems promising in case Higgs does not exist.
