Article mentions 2015 and 2016. I would hope this continues through the sale of the model. As most have mentioned they would want/prefer the "R",
and are going to wait for MSRP, seems one would be looking at a 2017 or later model.
Did the Boss program. It was very cool.
A GT Track program would be great and showcase some of the capabilities of the car in a controlled environment. So owners would not be out learn features of their car on there own.
