Dave Jackson,
You nailed it. "Sikorsky Innovations" is probably not the best name for a company division that is the lead on this particular project. All the innovative stuff is COTS from subcontractors. The systems SI is engineering don't appear to be especially challenging.
The motor supplier,
US Hybrid, makes PM drive motors that operate well above this aircraft's rotor speed. So I would speculate that some sort of reduction gearbox will still be necessary.
