What will the Xbox One sell in its lifetime?

Even though xbox one is ahead of xbox 360 at the same point in time, it reached more of its sales due to taking advantage of ps3 price point and Kinect which give it another push during mid gen. Assuming there won't be another Kinect miracle this time and ps4 wil keepl eating marketshare from xbox everywhere, I see this way.

Xbox 360 xbox one
US 44m 30m max
Europe 25m 15m max
Japan 1.6m 250k
ROW 13m 4m
Approx 84m 50m

The only place where I see a turn around is in US and a bit in Uk but ps4 will gain almost all marketshare lost elsewhere.

Let's say:

US: 20,000,000 - 25,000,000

EU: 8,000,000 - 10,000,000

RW: 2,000,000 - 4,000,000

WW: 30,000,000 to 40,000,000
