When the Tesla Model ≡ is unveiled, it will be not as one, but at least three body configurations. Two of those will certainly be a sedan and crossover. A third may be a wagon. Within two years a coupe and cabriolet would be presented.
There will be no delays of any sort, but there will be a steady, controlled, gradual rollout to worldwide territories. That is, Tesla Motors will prioritize US sales for much of the first twelve months of production. Right hand drive territories will be the last to get Model ≡.
Because of this, reservations will not be accepted for any location that is more than 12-18 months from initial deliveries. No one will be waiting three, four, or five years to get a car they put down a deposit for... But as capacity and production ramp up, some will unfortunately have to wait two years for delivery.
I humbly suggest that everyone who thinks there is 'no way' Tesla Motors delivers any of the Model ≡ before 2019 make sure they don't order one before 2019 -- so as to make sure they aren't disappointed.
