Momotaro is going to be this holiday's evergreen with New Horizon and Ring Fit Adventure, Konami's board-game is looking like it will surpass 1 million physical before the end of the year. And it's very likely that it end ups as Konami's best selling game in Japan of all time unless they prematurely release a sequel.
As I mentioned in the COMG thread a few weeks ago before the launch, 1.5 million is the floor for Momotaro. https://gamrconnect.vgchartz.com/post.php?id=9247616
