I'm kinda expecting some levels to use layer jumping, like what Nintendo wanted to do with the VB Mario title.

Based on this:

THeir reasoning of this is rather weak I know, but the concept seems to make sense when you consider that the 3D would work well with it.

Yeah, that seems pretty likely. Not exactly anything new, though, Nintendo's already used that idea in the 2nd Paper Mario, and the newest Donkey Kong Country, and probably a few other games.
