Xbox One vs Xbox 360 in the US – VGChartz Gap Charts – October 2019

Xbox One Vs. Xbox 360 USA:

Gap change in latest month: 314,618 – X360

360 really had some impressive legs. 

Xbox One on the other hand seems to really be running out of steam this year. 

They need to do what Nintendo did with the Switch; regroup, rebrand, learn from their mistakes, and come back swinging with the next system.

The back-and-forth dance of unaligned launches/holiday seasons continues. I wonder how long this will continue before one pulls ahead for good.

At what month number does Kinect come into play for X360?

Right where the big drop off starts, month 61. It launched in November 2010.

That's what I thought! Like it or not Kinect was a big hit for Xbox 360 and it helped the later years a lot.

Kinect likely added 20m to the lifetime sales of the Xbox 360. 

This one is turning out to be a very interesting slugging match; PS4 may be dominating its predecessor globally, but in Japan PS3 is putting up a good fight, and even gaining ground now that PS4 sales in the land of the rising sun have stagnated. Will be intriguing to see which one ultimately comes out on top.
