Soraya Saga: Xenoblade Chronicles 2 is coming out in 2017: UPDATE Shulk's VA may have hinted lthat they are in the middle of localization

I can see that happening tbh, they already have an engine for open world HD games through XCX some more focus can go to creating the world and characters which would speed things up in the 2 year period.

Switch has 3 open world games off the bat with Zelda, Odyssey and XC2.
