"I wonder if the reloft will transform the wings into supercritical airfoils?"
Wouldn't surprise me a bit, even if I've been out of the Aero Barrio for too long to make this anything but a WAG.
I believe that they also said they were putting the 777 winglets on the -8, TripSeven already has a supercrit wing and if you're going to redesign something, half measures ain't worth spit.
