Simple symmetry arguments applied to the third generation lead to a prediction: there exist new sequential Higgs doublets with masses of order $$\lesssim 5 $$ TeV, with approximately universal Higgs-Yukawa coupling constants, $$g\sim 1$$. This is calibrated by the known Higgs boson mass, the top quark Higgs-Yukawa coupling, and the $$b$$-quark mass. A new massive weak-isodoublet, $$H_b$$, coupled to the $$b$$-quark with $$g\sim 1$$ is predicted, and may be accessible to the LHC at $13$ TeV, and definitively at the energy upgraded LHC of $26$ TeV. The extension to leptons determines a new $$H_\tau$$ and a potential $$H_{\nu_\tau}$$ doublet. The accessibility of the latter depends upon whether the mass of the $$\tau$$-neutrino is Dirac or Majorana.
