I was just thinking, Super Mario 3D Land was an interesting game because of the perspective change coupled with stereoscopic 3D.
Does the Wii U support stereoscopic 3D? If 3D World features 1080p stereoscopic 3D @ 60fps with four players running around simultaneously, it might just be a really impressive title. Without 3D it'd more akin to Sonic 3D Blast.
Thoughts?
