Captain Toad: Treasure Tracker will be heading to Nintendo 3DS and Switch this year. While the 3DS version has no release date yet, the Switch version will be coming July 13 (same as Octopath). To entice Wii U players to double dip, this new port will include levels based on Mario Odyssey. There will also be split joy-con play on Switch, though not a full blown co-op mode.
