John, Model X and Model 3 are
John, Model X and Model 3 are two different stories IMO. M3 won't have cucumber slicing falcon doors and that kind of stuff, and it won't share the line with Model S.
Even with those limitations, more than 9000 Model Xs were sold in the last 6 months (that is more than 1500/month) and their production is still getting better. They are above 2000/week together with Model S.
