The insurance companies which insure commercial telecom satellite launches are EXTREMELY risk averse - I would be surprised if you see a commercial launch in any of the first eight re-uses of first stages. Government/science payload/R&D, yes. LEO or geostationary transfer orbit commercial, no.

edit: you might see a commercial flight with a never-flown-before prototype commercial satellite bus (example: like a geostationary bus the size of a boeing 702 with a novel never before tested type of ion propulsion stationkeeping system, or a new battery system, or something else weird).
