Xbox One sales are steadily outpacing the Xbox 360's nearly a year into their respective races.

Hasn't it been tracking well below the 360 during 2014? 

Yes.

Considerign the Xbox 360 was still supply constrained at this time in it's lifecycle and the Xbox one is freely avaialble....  That just means the gap would be wider.

This needs to be analyzed and better understood.  We all know the 360 was in short supply at launch,  but does the second chart indicate that sales for X1 are super front loaded?
