Nintendo has confirmed they’re removing both Bayonetta and Bayonetta 2 from the Wii U eShop.
Both games will be pulled from the Wii U eShop on September 19th. If you’re still playing them on the Wii U, you’ll be able to re-download them from your account after that date, so long as you owned them before they get pulled.
Both games will naturally stay available on the Nintendo Switch eShop.
A third game in the series, Bayonetta 3, is currently in development for the Switch as well.
