As far as Amazon rankings go the only thing that really matters is the monthly rankings. As of now it's:
http://www.amazon.com/gp/bestsellers/2014-11/videogames#1
#7 - Xbox One Assassin's Creed: Unity Bundle
#15 - Playstation 4 Console
#25 - Xbox One Limited Edition Call of Duty: Advanced Warfare Bundle
#46 - Xbox One Assassin's Creed: Unity Bundle - Kinect Sensor Edition
#49 - PlayStation 4 Destiny Bundle
#55 - Xbox One
#59 - Xbox One Special Edition Sunset Overdrive Bundle
The Xbox One had a great head start at the beginning of November. We'll see if the Playstation 4 can make up the November gap by the end of the NPD period.
I enjoy following the hourly rankings but it's hard to put much faith in them, they tend to be all over the place.
EDIT: It looks like much of this was covered while I was typing that in. Hopefully it's not too redundant.
