The focus point region of supersymmetric models is compelling in that it simultaneously features low fine-tuning, provides a decoupling solution to the SUSY flavor and CP problems, suppresses proton decay rates and can accommodate the WMAP measured cold dark matter (DM) relic density through a mixed bino-higgsino dark matter particle. We present the focus point region in terms of a weak scale parameterization, which allows for a relatively model independent compilation of phenomenological constraints and prospects. We present direct and indirect neutralino dark matter detection rates for two different halo density profiles, and show that prospects for direct DM detection and indirect detection via neutrino telescopes such as IceCube and anti-deuteron searches by GAPS are especially promising. We also present LHC reach prospects via gluino and squark cascade decay searches, and also via clean trilepton signatures arising from chargino-neutralino production. Both methods provide a reach out to m(g) similar to 1.7TeV. At a TeV-scale linear e(+)e(-) collider (LC), the maximal reach is attained in the Z(1)Z(2) or Z(1)Z(3) channels. In the DM allowed region of parameter space, a root s = 0.5TeV LC has a reach which is comparable to that of the LHC. However, the reach of a 1TeV LC extends out to m(g) similar to 3.5TeV.
