Got quick software leak (physical only for all three titles).
So Avengers digital must be >715K.
Mario with 50% digital split would be >2.3M, which is bonkers, should be outperforming Mario Odyssey outside of Japan. ACNH has been at 60% digital outside of Japan, so sounds like a 450-500K month.
Mario 3D All Stars selling 1Million in less than 2 weeks in Physical U.S sales is amazing, likely half the sales are digital so we could assume it sold around 2 Million in the U.S in September alone. I would say it probably sold around 5 Million Globally in September, seems like it might hit 10 Million Before March 2021.
