There was an official communication to US dealers on July 13, 2018:
" CHARGING CABLE - The previously communicated standard Multi-Function Charging Cable has been removed from the program and will be replaced with a standard Home Charging Cable, capable of charging via domestic sockets. This Home Charging Cable is not capable of Level 2 AC charging. As previously communicated, the preferred home charging solution for the customer is the Jaguar approved wall box which itself comes with a tethered charging cable."
I remember seeing the multi function Charging Cable in the pre-production frunk of the demo vehicle but I now understand that is not what we are getting.
