There were two big things missing for me that I was hoping to get tonight. First was delivery estimates. They have given general production numbers and rough estimates on when you receive the car if you order today, but existing reservation holders have no idea when they will have the option to purchase and/or receive the car or even the expected lead time between purchasing and delivery. Second thing missing for me was an idea of options for the car. There is still no real information on what options will be available for the car, when they will be available, and what they will cost.
These two issues mean there is still very little information for reservation holders. There seems to be a window of about $15k and 6 months for the cost and potential delivery date of the car.
