3D Land and World are NOT a sidescrollers. What's more, there isn't a single 3D game like them. In 2016 they're way more unique than the "new types of platforming games," you speak of. I'd take another completely new form of Mario if they nailed their idea as well as they did the 3D World games.
That said, you know, I do think a new 64 type game is something that should be done at some point.
Obviously they're not literally sidescrollers, but they're clearly built to satisfy fans of this type of platformers at the expense of those who enjoy a more action-adventure style. And there's absolutely nothing unique about them because Wii U already has a plethora of quality 2D precision platformers in its library, without even mentioning other systems and indie games, while Yooka Laylee is the only surviving example of the 64 era platforming template.
