I don't see why so many here keep saying "there are so many factors here". There's only 1 factor....the number of production lines (just like the number of registers open at your local supermarket). The design & testing schedule is the design & testing schedule....nothing much you can do about that schedule. But production is much easier in terms of schedule....it IS a matter of money. Guestimating Tesla needs 1 production line per 100,000k pre-orders, they simply would need to build 3 more lines to cover this years orders. Look for Tesla to pay for the additional production lines by asking you for $4k per pre-order to get your lock in the production queue.
