I don't think that the mustang is a good example - mustangs are renowned for being a v8, and people rightfully get ribbed for having the "baby" mustang.
Similar thing in Australia - the straight 6 turbo Ford engine when tuned was more powerful, but the market mostly wanted a v8
But like I said - anyone that wants a twin turbo Z will buy one NOW.
At the end of the model cycle, Nissan can scoop up the last of the potential buyers with the new version.. It's very common to put out a "special edition" with a few freebies to finish out the final sales of an ageing model
It's the same reason that a Nismo version doesn't come out immediately - they want people to buy the first release, then perhaps trade in or buy new again when the Nismo comes out
Similarly, have you noticed that sports cars like the Supra and Z release as automatic only first - to suck in the early adopters, and then get them again a couple of years later when the manual comes out.
It's all about avoiding cannibalising your own sales of high margin vehicles
