Predictably, Arceus joins the ranks. Not a whole lot of other changes, though ACNH inches closer to passing Super Mario Bros. SSBU & BOTW continue their march to 30m and Super Mario Party continues towards 20m. Bowser's Fury should join the ranks later this year. I imagine that Switch Sports and Forgotten Land could join 10m as well too. Obviously SV will do it pretty easily. Also, Mario Party Superstars should join 10m before long as well!
