The current central values for production and decay rates in various channels of the 125 GeV state differ from those predicted for the SM Higgs. Fitting, at least approximately, the observations is entirely possible within the NMSSM which contains multiple Higgs bosons that can mix with one another. There are many options for fitting the 125 GeV state rates while having a second CP-even Higgs boson that is: a) at 98 GeV and fits the old LEP excess b) degenerate with first CP-even Higgs, both close to 125 GeV) at 136 GeV and providing a more comfortable description of the Tevatron Vh with h-> b bbar excess while giving a small excess in the two-photon final state at this mass. I review these options and the ensuing implications for dark matter, sparticles and the other Higgs bosons, focusing on future probes of the three different model possibilities
