Joker-
Your "well informed" journalist is not that well informed! The S-92 has 4 main rotor blades (last time I counted) and will have them for the next decade, anyway. The vibration is very nice, thank you, with levels that are better than the President's S-61, thanks to the 4 (that's four) main rotor blades, and also the very good computer driven vibration absorber system that we use.
We are producing rotorheads and airframes now for the Lot I and Lot II of production, and they have those four blades, too. The 1305 engineering reports that the FAA now has all reference the 4 blades. The FAA will shortly issue the Type Inspection Authorization (TIA) and will be testing very shortly, and will certify that 4 bladed S-92 by the end of the year.
I suggest that the journalist ring me up. I would be glad to discuss this stuff with him directly. I am not hard to find!
Here is some info on the 92 from the Sikorsky web site:
