Personally, I'd rather have neither. I'm not really sure why, just because Nintendo did a Galaxy 2 (which they shouldn't have, because MG1 was far better), that now they fully expect Nintendo to just do direct sequels to their 3D Mario games. I want them to get off of doing that.
I want them to take a fresh approach. And honestly, I still want now what I've wanted out of a 3D Mario a long, long time: a 3D game where you are ACTUALLY running around the Mushroom Kingdom/World (not just a castle with magic paintings), where you can run around massive representations of, say, Grassland, or Desert Land, or Giant Land, Ice Land, etc. Even throw in a condensed Dinosaur Island, and have a hidden pipe to Sub-Con as a special bonus area (instead of the "Special World" concept). THAT is what I want. I want an epic 3D Mario that actually lets me run and play around in the same sprawling, crazy kind of world that Mario 3 and 4 (World) depicted. That's what I, as a longtime Mario fan, want to see.
It doesn't even necessarily have to be "open world". It just need to have huge, awesome levels, that are not just little strips of platforms on land or in the air, but are actually big, organic, sprawling 3D Mushroom Kingdom environments, with everything you could imagine under the Angry Sun in them. I don't know if that will ever happen, but that is what I want.
Regardless, what I don't want, is another Mario space adventure, or game with the water pack, or even another 3D World type game (or another castle with magic paintings for that matter). I want them to take a different direction, no matter what they do next.
