I think the SuperDuty will
I think the SuperDuty will keep it's unique look to some extent by having a Super-Duty-like front grille and a completely different, Super-Duty style bed mounted on a stronger frame.
But the cab will be the F150 cab for the most part, which I think is smart, because Ford has been at a cost disadvantage with the two totally different trucks versus their two competitors since the big departure back in 1999; and considering the time, effort and dollars put into this new, mostly-aluminum cab; I don't see how Ford can do better with a second, all-redesigned, aluminum cab specifically for the SuperDuty.
