No, and you know why, right? Because everyone wants jets, although it costs them more. And frankly, the way Beechcraft charges for King Air parts, I think the KA line eventually will end, too. Many Citations are today cheaper to run than a King Air just because of Beech's pricing.
The P180 is the only real leap in technology in aviation in those 40 years. And the market has largely rejected it, because aviation is as conservative as the Spanish Inquisition.
