The likely drop of s/x units could explain why Elon wrote tiny profit in 1q19. It's otherwise a puzzling statement, knowing that EU and China will boost sales of the premium M3. It takes more than three M3s to make up the loss of one s/x, given that s/x is twice the price of M3 and 1.5x of the gross margin.Btw, I asked that question before the news hit the wire.
I would have guessed 15-20K before they got rid of 75.
Now with apparently no new replacement planned and no refresh planned, I would be surprised if they sell 15K.
