Thanks flateric. The Mi-8X designation led me to this:
"Mil is funneling the bulk of its resources into three major programs: the Mi-28N night attack helicopter, the civilian Mi-38 and dual-purpose Mi-8X. The three helicopters will share the same glass cockpit, blades, rotors, gearboxes, engines and flight control system, making transition from one to another easier for operators."

and this from Flight
"Helicopter Holding will market a unified "trio" of next generation medium-class (11-15t maximum take-of weigh) helicopters - the civilian Mi-38, the Mi-28N anti-tank helicopter and the Mi-8X dual-purpose helicopter. The three will share engines, gearboxes, main and tail rotors and onboard systems.
CIS certification
Having completed manufacturer's trials last year, the Mil Mi-38 is undergoing certification with CIS aviation authorities in the view of service entry in 2011. The helicopter has a hingeless mast, composite blades and anX-like tail rotor. "Flight-tested on an Mi-38 and Mi-28N, these innovations will find their way onto the Mi-8X, promising a considerable reduction in operating costs per flying hour," says Mil general designer Aleksei Samusenko. UTair, the world's largest commercial rotorcraft operator, and other Russian companies placed tentative orders for more than 100 helicopters. "We are going to complete the Mi-38's certification and production preparations in three years, and then apply its innovations to the Mi-8X," Samusenko says.
Helicopter Holding says the Mi-38 will supplement, rather than supersede, the Mi-8/17 in the civilian markets, particularly in regions such as Europe, leaving tougher territories, such as Siberia and Africa, to the more robust Mi-8/17. But the Mi-38/Mi-8X pair will face stiff competition from Eurocopter, Sikorsky and AgustaWestland medium-class designs.
