Maybe this has been mentioned but the PS4 was actually launched a week after the XBox 1 in other regions. So IGN are taking worldwide sales and stating the XBox 1 launched 5.5 weeks ago compared to 6 weeks ago. That is only true for the US and I think the PS4 has sold a lot more outside the US. But then again, the PS4 launched in more markets that the XBox 1 hasn't had a chance to impact on yet.
