I don't see the i8 every getting to serious production unless either 2 things happen -
The price goes way up in order to retain the most noticeable features of the concept, or
those features disappear and the car get's dumbind down to something more ordinary.
The 3rd and perhaps most likely scenario is that they hand produce a very small number at a loss as an R&D/marketting exercise.
