Nikkei: Super Smash Bros. Ultimate topped 5m at its first 3 days (retail sell-through+digital)

Do we know digital percentage?

So the person who bet only 5m at most for December does he get premium brand of crow or the cheap brand?

Is this the best opening for an exclusive ever?

Permabrand

For a Home Console very likely. 

Obviously. Any game with Daisy in it will break sales records. I hope Nintendo is taking notice!

In the first 3days, I think Sun/Moon is bigger than Smash Ultimate based on Japan and a few European countries and it was very front loaded.  Smash Ultimate leg in the first month sales is going to surpass or perform closely to Sun/Moon IMO. 

if handhelds are included , I think Pokemon Sun and Moon sold 5.5m in 3 days. not sure.

Egad!!!
