Someone has explored the implications of this putative discovery of the Higgs particle.

They analyzed it in two subsets of the Minimal Supersymmetric Standard Model:
mSUGRA: free parameters m
0, m
1/2, A
0, tan(beta), sign(mu)
and
NUHM2: free parameters m
0, m
1/2, A
0, tan(beta), mu, m
Am
0 = mass scale of the spin-0 superpartners of the elementary fermions
m
1/2 = mass scale of the spin-1/2 superpartners of the gauge particles
m
A = mass scale of the heavy Higgs particles predicted by the MSSM
For both mSUGRA and NUHM2, m
0 >~ 0.8 TeV, pushing the squark and slepton masses into the multi-TeV range. Those particles may thus be difficult to make with the LHC.
However, m
1/2 is less constrained, meaning that the LHC may be able to make gluinos, neutralinos, and charginos more easily.
Both mSUGRA and NUHM2 tend to produce too
much neutralino dark matter, except if the lightest neutralino is higgsino-like, with a mass around 0.8 TeV. However, that would bump the bino, wino, and gluino masses into the TeV range. Especially the gluinos, which are otherwise the easiest for the LHC to make.
Neutralinos = mixtures of the bino, neutral wino, and neutral Higgsinos
Charginos = mixtures of the charged wino and charged Higgsino
The lightest supersymmetric particle is usually expected to be a neutralino.
So this putative discovery may mean that it'll be awfully hard for the LHC to detect supersymmetric particles.
