Given the recent announcement:

http://gamrconnect.vgchartz.com/thread.php?id=172902&page=1
XB1 sold 1 million in 24 hours
Out of those 1 million sales,
Let's assume that
US + Canada : 600 K - 700 K
Others : 300 K - 400 K
let's also assume that this sales figures extrapolate to the future exactly like that...
In North America, roughly speaking
PS4 : 1000 K
XB1 : 600-700 K
This is a 30-40% deficit on XB1's account, impliying a 37-41 % NA market share for XB1. Again perfectly aligned with my original expectations (35-45% in NA).
Playstation 5 vs XBox Series Market Share Estimates
Regional Analysis (only MS and Sony Consoles)
Europe => XB1 : 23-24 % vs PS4 : 76-77%
N. America => XB1 : 49-52% vs PS4 : 48-51%
Global => XB1 : 32-34% vs PS4 : 66-68%
