Plasma Wakefield Acceleration has demonstrated impressive progress in the last ten years. Acceleration gradients of 50 GeV/m have been sustained in meter-scale plasma to double the energy of initially 42 GeV electrons from the SLAC linac in a landmark experiment. A straw man multi-stage design of a 1 TeV CM e+e- collider based on the PWFA concept has been introduced which specifies the parameters for the drive and the accelerated beams. The next phase of this research will focus on achieving many of the requirements of a single stage of a multi-stage PWFA-based collider. These include the necessary charge, energy spread, energy extraction efficiency and emittance preservation. This is the purpose of the FACET facility now under construction at SLAC. Researchers are beginning to consider the possibility of using ultra-relativistic proton drive bunches to accelerate electrons as well to perhaps go beyond 1 TeV. I will discuss these exciting developments in this talk.
