God, I hope so.
If Nintendo doesn't bring it themselves, I hope they finally open up and let interested 3rd parties pick up their passed over stuff like Tackt of Magic, Disaster, Soma Bringer, ASH, Jet Impusle, etc. They used to let Atlus USA publish their unwanted imports (Cubivore, Polarium Advance), I'm not sure what changed this gen?
edit: Forgot to mention it, but being Motion Plus compatible likely greatly improves Reginliev's chances of being brought over. I imagine NOA and NOE are pretty hungry for M+ games to help feed the peripheral's fast growing audience, and the only other games on the table are Spawn Smasher and Zelda, which are both probably a ways off...
