Tesla is shifting to CCS. European Model 3 will have CCS socket (Combo2, similar to Combo1 for US market).
All SuperChargers (with time) on our continent will be retrofitted with CCS cable. Preparations are already in progress.
Model S and X owners will be able to get (soon) CCS adapter so they could use public 50-350kW charging networks
like Model 3.
I suspect Tesla will start shipping Model S/X with CCS socket as soon as 90+% Supercharger locations will have CCS available.
Maybe somewhere mid 2019. I'm absolutely sure Tesla will not have two sockets forever.
Question is, when will switch happen in US/Canada
Question 2 - who is the first shaking hands with Tesla on SuperCharger network access?

Just a remark. Teslas with CCS socket will not be able to use current ChaDeMo adapter.
I suspect CCS-ChaDeMo adapter will not be made due to redundancy (most charging stations have both, ChaDeMo is slowly abandoned.
