Well in the original Model S reservations they moved up folks who had bought the high margin ones to the front of the line so that they could show a profitable quarter early on. If you looked at their build orders for that first quarter or so it was waaaay slanted towards the more exotic versions. I would expect them to do the same for the Model 3. While it frontloads the profit, that can bootstrap the rest of the system.
They're doing the same for the Model X. P90DLs got priority, then P90Ds, and now I believe the 90Ds are starting to show up. 70D orders will probably be waiting until the second half of this year.
Do you mean S 70Ds? According to modelxtracker.com, no X 70Ds have been delivered yet. That's not a comprehensive list, but I'd expect to see some there if they've been making deliveries.
