Captain Toad: Treasure Tracker, Mario Kart 8 Deluxe, and Donkey Kong Country: Tropical Freeze have shown that Nintendo is more than willing to flesh out Switch’s library with Wii U ports. And if a new report is to be believed, the next Wii U game to make the jump could be New Super Mario Bros. U.
Comic Book reports multiple sources, who are purportedly “linked with Nintendo,” have suggested New Super Mario Bros. U will be updated and re-released for Switch “as early as this year.”
