I just re-checked the email I received about Model X deliveries in Australia and I shouldn't have used the phrase "late 2017"; that was from memory and it turns out that the advice was that reservations made now - as distinct from those that already have a reservation - could expect a delivery anytime in 2017 and, worst case, early 2018. I was keen to order a Model X but didn't want to wait until an unknown point in 2017 or 2018 so that's why I ordered a Model S. But I think I should still go ahead and plum for a reservation slot on a Model X and was just wondering what others had been told.
