Comic Book claims that the same sources that provided detailed info on games like Mario + Rabbids: Kingdom Battle, have suggested a Switch port of New Super Mario Bros. U is coming in 2018.
The potential title for the port would be New Super Mario Bros. U Deluxe and would include the original New Super Mario Bros. U and the New Super Luigi U add-on, both originally released for Wii U. Furthermore, New Super Mario Bros. U Deluxe for Switch would include additional new content.
Stay tuned.
