  17. CLIC • Given high priority by European strategy • Conceptual design for 3 TeV (CDR exists), feasibility demonstrated, many components developed, staged approach starting at 380 GeV, which will follow physics findings • Project plan to be developed for 2019 • ILC • Japan might offer to be the host (decision process is ongoing since several years) • Quite mature (TDR exists) for 500 GeV, 250 GeV under discussion • DOES NOT SEEM TO BE THE PREFERRED WAY FOR NEXT PHYSICS
