Well yeah the challenger will not always be the shiny new limited model that it is now. But just in comparison to the S197 mustangs I doubt you will see even half as many challengers. I think it is a very timeless design and between that and actual production/sales numbers it will not become played out the way the mustang has. And if we end up with a repeat of the 70s, production could stop after 3 model years while the mustang keeps on going, that would limit its presence as well.
