Nintendo Switch's porting of the Wii U library continues after new reports suggest that Nintendo is working on bringing over New Super Mario Bros. U for the Switch.
The report comes by way of Liam Robertson for comicbook.com. Robertson says that sources who have previously provided accurate details for Nintendo projects like Mario + Rabbids, says that the New Super Mario Bros. U port for Switch will include the paid Super Luigi U DLC and possibly even more new content.
Other Switch re-releases of Wii U games like Donkey Kong Country: Tropical Freeze and Captain Toad: Treasure Tracker did indeed come with new modes and content, so this wouldn't be a huge surprise. To what extend the new content could look like is unknown however.
No release date was confirmed, though Robinson suggests that the game could come out as early as this year referencing remarks from Nintendo about how they still have unannounced projects for 2018. Nintendo's E3 2018 presentation was noted for its lack of games and heavy focus on Super Smash Bros. Ultimate.
The Wii U was famous for having critically-acclaimed first-party and exclusive titles, but the system itself did not reach a wide enough audience at the time. The Switch in comparison has been a huge success for Nintendo and the system is still selling particularly well. This makes Wii U ports particularly attractive as it's a way to get overlooked Nintendo games into the hands of players who skipped the Wii U for the Switch.
