Eh, Amazon rankings for month : PS4 ahead.
The deal for X1 was also much better than the previous deal for PS4 :
$175 X1 : http://www.gamespot.com/articles/how-to-buy-a-new-xbox-one-for-175/1100-6426937/
$275 PS4 : https://games.yahoo.com/news/buy-ps4-275-194900387.html
I do think the margin will be low, because like last month, sales will be terrible.
