Japan sales (Week 21): Media Create/Famitsu/Dengeki - May 21-27, 2018

[Megiddo]

Assuming that the Switch sells the same numbers in November-December as last year (about 1.3 million) the Switch will need an average weekly sales of 77,802 from June to October to hit 4 million sold in Japan in 2018. That's only going to keep going higher and higher as more weeks selling 35-40k roll by.
