As Acer said a couple of days ago, the NH90 is the ONLY Full Fly-By-Wire helicopter in production today.
The RAH-66 was indeed an advanced FBW system, but the program has been cancelled and therefore it does not count anymore.
The NH90 is using a double attitude reference system with Ring Laser Gyro's which provides the input for the FBW system. There is a third one as backup (if all else fails).
The output to the Main Rotor Actuators is indeed analog, but the control laws can still be tuned to the needs and you can get rid of nasty coupling effects (so it is not only for basic damping etc.).
Of course other manufacturers are experimenting with FBW and in time this will probably be common practice...
