Given the delay and then the weak sales, this isn't a surprised.
I wonder if Hogwart's Legacy's Switch version will get canned as well.
Well, if it does get cancelled, it won't be for lack of sales from the other versions. Much to the chagrin of some on this site, I'm sure. And having played the game on PS5, it's not an especially impressive game, visually. You could definitely trim back on some effects and draw distances to get that to work on even a device as perpetually underpowered as the Switch, at least when docked.
As for Midnight Suns, it's a card-based XCOM Marvel re-skin. You have to wonder how much they realistically expected to sell to begin with. I'm sure releasing the main versions in early December did the game no favors, either.
