The 3D is great, I always use it. I'm better at jumping platforms in Mario 3D Land and aiming shells in Mario Kart 7 due to the added depth and distance perception. I mean, going back to a console, the difference is really noticeable.
While it's not crucial and won't be a dealbreaker, I would be bummed if it doesn't return. I hope the next system, at least the handheld, supports 3D.
