If the model S is a comparison, expect delays in production. However, a high percentage of people with a reservation will also delay or cancel. My model S reservation was in the 4000s and my model S vin number is in the 2000s. To get an early model S, we had to order an 85 with air suspension. There may be similar requirements for the model X.
I didn't realize the attrition rate had been that high for Model S. I might expect it to be higher for Model X since they seem to have been accepting or even encouraging, Model X reservation holders to convert to Model S.
