We present updated global fits of the constrained Minimal Supersymmetric
Standard Model (cMSSM), including the most recent constraints from the ATLAS
and CMS detectors at the LHC, as well as the most recent results of the
XENON100 experiment. Our robust analysis takes into account both astrophysical
and hadronic uncertainties that enter in the calculation of the rate of
WIMP-induced recoils in direct detection experiment. We study the consequences
for neutralino Dark Matter, and show that current direct detection data already
allow to robustly rule out the so-called Focus Point region, therefore
demonstrating the importance of particle astrophysics experiments in
constraining extensions of the Standard Model of Particle Physics. We also
observe an increased compatibility between results obtained from a Bayesian and
a Frequentist statistical perspective. We find that upcoming ton-scale direct
detection experiments will probe essentially the entire currently favoured
region (at the 99% level), almost independently of the statistical approach
used. Prospects for indirect detection of the cMSSM are further reduced.
