  Assuming that the recently discovered particle at LHC is the Standard Theory
(ST) Higgs Boson, we compare the ST predictions of M_W and Sin^2 theta^lept_eff
with the experimental values of these basic observables. While the Sin^2
theta^lept_eff prediction is in excellent agreement with its experimental
value, that of M_W shows a 1.33 sigma deviation. Implications of these
comparisons for possible future developments at LHC and a future GigaZ linear
collider are briefly discussed. It is also pointed out that these comparisons
are consistent with the conjecture that the newly discovered particle is indeed
the ST Higgs boson.
