Bell proposed the V-44.
Boeing proposed a Side-by-Side.

Bell's future vision is filled with Tiltrotors (V-22, BA609, Eagle
Eye).

Boeing's future vision is filled with canard wing stop rotors's
(Dragonfly).

What is Sikorsky's future vision? Variable Diameter Tiltrotors?
Refinement of the convntional helicopter? Are they working on any
flying prototypes?

Just curious.
