This is a comparative analysis from the Data I gathered from this site.

The numbers below are entirely in line with my original projections about the US market share, posted here:

http://www.vgchartz.com/article/251427/ps4-vs-xbox-one-us-launch-sales-comparison/

Basically, I am estimating the North American market share between PS4 and XB1 to be...

XB1 :  Around 35-45%

PS4 :  Around 55-65%

Currently the preorders market share for XB1 is 45% overall, and 42% for third parties, which is more representative in the long run. Those numbers will more likely improve in favor of PS4 in the upcoming months / years due to the network & catapult effects from the rest of the world, in addition to the more price sensitive casual crowd, who will favor PS4, and improved supply constraints.

Isn´t there a one week difference between those numbers?

* Correction :

There is a slight mistake with the Need for Speed Rivals numbers for Xbox One, which is supposed to be around 38K. This is an estimated* number by interpolation, since the data was simply not available. However, this is a conservative estimate since we at least know the maximum amount that it can be (less than 45 K). The effect on the overall results were tiny at best, so I didn't bother correcting it.

Yes.

Great work man, must've been time consuming!

They are all taken from the Nov 09, 2013 Data (latest) on the site. just caution on the mistake regarding the NFS Rivals for Xbone though.

But let me know if the data is updated. I will update the tables here as well.

Exactly, so some of the X1 games are one week behind in preorders. COD:Ghost on X1 for example should pass the PS4 version when the next edition comes up. I do not know how much difference it will make bu alot of games usually add a ton of preorders the week before relase.

Don´t get me wrong, you have done a commendable job, but I think you should compare numbers for the same number of weeks ahead of launch for each games, just a tip :).

Shouldn't these be compared by their "1 week left" pre-order numbers instead of their Nov 9th numbers?

The issue is that this site preorders are way wrong... PS4 did way way way better than they predicted.

And I will guess now but Xbone will do worst than what they predicted.

Well like always hapened with the preorders chartz.

The thread has been updated to reflect the sales projection based on the Launch Sales, instead of Preorders.
