Check out this interesting video Steve Trimble of The DEW Line shot of Sikorsky's presentation at the Oskhosh AirVenture on the future of it's high-speed coaxial rotor helos. Pay particular attention to the part about construction on the prototype S-97 high-speed military bird being set to begin in a "month or so." The first flight of the bird is tentatively scheduled for late 2013 or early 2014.
