The Wii and Wii U are still getting releases in October of 2018.
Along with the Switch, the legacy Nintendo platforms will receive their annual Just Dance release with Just Dance 2019, scheduled for release on October 23. Artists confirmed for the game include Bruno Mars and Cardi B ("Finesse"), Daddy Yankee ("Shaky Shaky"), and Mayra Veronica ("Mama Mia").
They actually did it. Those madmen! So, now if someone asks what were the last 5 games released for the Wii, the answer has been updated to Just Dance 2015, 2016, 2017, 2018 and 2019. And who says the Wii U is dead? They're still games coming out for it. Stay back Switch, you vulture!
