I wouldn't count it out just yet.
As a turboprop in normal flight mode she has the potential of being very fuel efficient with those small wings (less drag) and huge props (huge props = less power needed to maintain speed). And since the props are coupled, perhaps one could even turn one engine off in cruise?
Obviously she's going to suffer from only being able to take off with a certain amount of fuel vertically which will limit range, but maybe they can fill her up more if she does the rolling take-off with the nacelles in the 45 degree position?
I find this aircraft terribly exciting. It might just be the answer to everything.
