Square-Enix released SaGa SCARLET GRACE: AMBITIONS digitally for the Switch in Dec. 2019. Fans were happy to see the game get a localization, but many were hoping for a physical release as well. While we still don't have any official confirmation on that, there's some retail evidence pointing to that physical release happening.
Play-Asia has recently added a bunch of listings for SaGa SCARLET GRACE: AMBITIONS that are different from the Japanese retail version. These listings all say that preorders are expected to open soon. That goes along with a new listing on Amazon, which unfortunately doesn't have any release date info either. Still, with both retailers adding the listing recently, it certainly seems like something is up.
