  WW scattering is dominated at high energies by their longitudinal components,
which are the most sensitive to the nature of the electroweak symmetry
breaking. Prior to the discovery at the LHC of a Higgs-like particle,
unitarization tools were extensively used to show that, in the absence of a
light Higgs boson, new resonances resulting from the would-be
strongly-interacting electroweak sector would appear, and furthermore these
techniques would approximately predict their masses, widths, and signal
strengths. With the discovery of a Higgs-like particle now firmly established,
we re-investigate these techniques assuming this particle couples exactly as in
the SM, but still being open to the possibility of an extended symmetry
breaking sector. While the SM itself is free from problems with perturbative
unitarity in the electroweak sector, "anomalous" self-couplings of the vector
bosons -- low-energy remnants of such higher-energy symmetry breaking sectors
-- are easily shown to re-introduce them. We demonstrate how new resonances
should still appear in the scattering of EW vector bosons after imposing
constraints from unitarity, and we discuss their ability to be probed with
current and future LHC data.
