Mario Kart 8 is 720p.
Having actually been at E3, Bayonetta 2 is fairly good looking as well, probably better looking than Mario Kart to be honest. From the trailer X looks like it's better than anything else though.
Mario 3D World looks better in motion than people think, but it is basically a very souped up version of 3D Land, not the Galaxy killer everyone wanted.
DKC: TF looks like a game that started on the Wii.
Graphically I'd say
X > Bayonetta 2 > Mario Kart 8 > Mario 3D World > DKC: Tropical Freeze
