Inventions and synergies with global and national goals are rapidly improving the prospects for a high luminosity muon collider at the energy frontier. Analytical calculations, numerical simulations, and technical innovations are coming together to make a strong case for a series of machines to be built, where each one is a precursor to the next, starting with the luminosity frontier machine at Fermilab, "Project X", and continuing through the upgraded neutrino physics programs. The ultimate machine will be an energy-frontier muon collider. In about 4 years, the LHC and Tevatron will point us toward the desired energy of the next lepton collider. At that time we must understand the needed technology and be ready to build the appropriate muon collider.
