i mean if what you're talking about is a banjo or mario 64 kind of platformer, the last good one of those was probably psychonauts almost 10 yrs ago. before that, for 3d adventure, the last really good one that wasn't a zelda title i remember was beyond good & evil and that sold like shit (and maybe ico and shadow of the colossus on ps2). so the genre is on life support at best.
splatoon's single player will be interesting, as it seems to have some platforming/adventure elements to complement the third-person action/tactical shooter trappings, but we'll see how that turns out. i mean by your standards i'm not even sure if a new galaxy game would be 'proper' 3d if captain toad doesn't qualify, because in many ways galaxy and captain toad are conceptually very similar.
captain toad and splatoon, then. xenoblade will be too different. zelda, obviously, but that was your initial point. (wind waker hd?) also don't see why bayonetta doesn't count.
