It was a blink and you'll miss it moment, but Elder Scrolls: Blades was finally given some semblance of a release window for Switch during the surprise Nintendo Direct Mini that I'm still reeling from.
Released in Early Access on mobile devices back in April of 2019, Blades has kind of just been chilling in the phantom zone without a release date. Eventually a potential 2019 window changed to a dry "2020," but thanks to said Direct we now know that Blades is arriving on Switch in "spring" of this year. Given that the Switch platform typically shies away from Early Access programs, it'll likely be a full version of the game launching alongside of a huge update for the mobile edition. For reference, you can find the confirmation at 24:00 in the Direct.
As a reminder, there aren't plans to add touch controls for the Switch port right now (though motion is a go), and it will require an online connection. Hopefully Switch owners will just walk into a version of the game that's less predatory, as strides have already been made on that front on mobile.
