excellent question. my guess is they are just not where they want to be?
My thought exactly however if this is the case when will they ever be. Holyshit i follow exotics all over the world no other mark would do what Honda has done with the NSX brand seriously 2003 Honda started with the replacement of NSX 1.0 we are now at 2016 13yrs later and still have no idea of the true capacity of this car what are they hiding from. As soon as the production cars are in the hands of Joe public and the true media journalists have an indication of how the NSX really is then all will be known so why hide the facts now.
As for production release anyone outside of the USA will have to wait at least 1-2 yrs for delivery from now as for hype that will be 15yrs in the wait.
