A burning question is:-
What is Sikorsky doing for the S-76D test?
Possibly nothing. The D model is not a new helicopter, just a C++ with some improvements. Same 76 Type Cert, so I don't think they have to do as much proving work as if it was a new design. Just like Eurocopter with the EC225, it is on the AS332 Type Cert. Saves a LOT of time and money if you can do it that way.
