I sincerely doubt a "super-futuristic" aesthetic is going to catch on in the mainstream. One of the reasons the Model S has done so well is because it resembles other large luxury sedans that it competes against.
One very thing in particular about futuristic designs, to include many recent domestic cars (like the new dodge sedans and sports cars) is little vertical space given for windows. In contrast, one of the great things about the Porsche 911 design is that you have incredibly clear 360 views with big windows. That's a major design feature that separates cars that are in continuous production for over 50 years and those that need design refreshes every few years.
