Elon commented that autonomous driving is coming faster than many surmise.
If the car becomes self driving and self aware, there will be little reason to have a display behind the wheel.
The positive trade off, is that without the display, the view of the road will be less obstructed, and a more pleasing view out the windshield will give an improved view of the road.
I predict the new interior will provide an even larger display, for additional information to the driver, as well as easier to view maps.
No matter, lots of interest in seeing what the new interior brings.
If the new interior is not well received, then the prices of used, pre refreshed, Model S/X should be solid.
