Why no boost for XBOX ONE this week in USA?

[Zekkyou]

The X1 is possibly under tracked, but i wouldn't necessarily say by much. I expect FH2 and SOM simply negated a lot of the drop the X1 would otherwise have seen.

This seems especially likely since the PS4 also saw a drop from last week (more so than the X1), despite SOM also selling 270k on the PS4.
