We knew it was coming thanks to Nintendo of Europe showing it in an image, but now it has been made official. Bloodstained: ROTN will be coming to the Switch, while the Wii U version has been cancelled.
A kickstarter update was put out where Iga stated that “the situation has drastically changed after the release of Nintendo Switch.” While it had made sense to include Wii U during the campaign that is no longer the case due to Nintendo shifting their focus to the Switch,
It continues
“This change made it difficult to receive the necessary support from the hardware maker, which has led us to drop the Wii U development and shift the development to Nintendo Switch,”
If you supported Bloodstained on Kickstarter , there is an option change their backer survey platform from Wii U to Switch or any other version, or other versions to Switch. I already changed my platform of choice on the backer survey, from PS4 to Switch. The option is there already.
