Bayonetta and Vanquish are getting remastered in 4K for the Xbox One. The official Microsoft store has listed a bundle for both games.
Bayonetta was first released as a multiplatform game for PS3 and Xbox 360. It was later ported to the Nintendo Switch along with the second game that involved Nintendo as a publisher. Since then, they have announced the third game in collaboration with Platinum Games and it is confirmed for the Nintendo Switch.
While the Bayonetta sequels are exclusive to Nintendo Switch, the original game ended up on PC with a 4K and 60 FPS supported port. It appears that users on Xbox One will be able to enjoy Bayonetta 1 and Vanquish in 4K and 60 FPS.
Both of these games were found on the official Xbox One store so there is no doubt in this being an official announcement and not a mistake. They are also available to purchase in a bundle. The 4K and 60 FPS support will be likely for the Xbox One X while it is not confirmed what resolution these games will run on the original Xbox One.
If you are interested in buying both of these games, the release date for both of these games is listed on February 18, 2020. Sega is listed as the published while the description confirms this is the first time these games are getting “remastered” for the Xbox One. There are no additional details on what kind of improvements are expected aside from the improved resolution.
Bayonetta already runs at 60 FPS on the Xbox 360 and can be played through backward compatibility support on Xbox One. This version runs at a lower resolution of 720p so this is an improvement in any case.
