Important update on 60kWh (I updated my original post as well): I spoke with my Product Specialist by phone 8/8, and he said that the Supercharging information I got at the showroom has been superseded. The official word now is that Supercharging details for 60kWh cars will be announced in September, and it may or may not require addition equipment in the car. For those folks who go ahead and Finalize 60kWh now, once those details are released, we will have the option to switch to 85kWh if that sounds like the better option when all details are known, with no delay in delivery.
