Notice what's missing? An X-2 configuration. Sikorsky management must realize that after a billion+ dollars invested in a dead end technology, they need to play catch up on winged configurations with tilting rotors. They've done concept work with rotor blown tilt wings before, we'll see if this is a viable path in and of itself, or just a stepping stone to a tilt rotor. No pitch fan in the tail indicates these rotors have cyclic and probably flapping, so it's not a traditional tiltwing and that's a good thing. The hybrid business is green washing, the real point of the project is the rotor / tiltwing configuration.
