Breath of the wild doing really good.
Undertracked here it seems by 700k.
Don't forget that VGC doesn't include digital, so unless it had the worst digital sales rate ever then the undertrack would be a fair bit less than that.
Actually, if around 16 or 17% of Zelda sales are digital (would actually be below the average digital %) then VGC would be almost spot on. So depending on digital, could actually be a bit overtracked.
Bet Shiken that COD would outsell Battlefield in 2018. http://gamrconnect.vgchartz.com/post.php?id=8749702
