The hardware chart on Amazon is going to look so weird this month. Lots of TTK sales on Amazon have been attributed to August, so even that will place relatively low in the monthly rankings.
Harking back to August's final monthly standings I think we can put PS4 in the win column, even though tere's only one PS4 on market sku in the top 100 and there are 3 (I think) Xb one on market skus.
