I'm not so sure it's certain the XBOX One will rule America this time around, I think the numbers will be a lot more even. Titanfall is one of the best next gen games so far but the fact that it's on PC/360 and the fact that it's multiplayer only are both strikes against it. Infamous comes out at around the same time for PS4 as does Driveclub so it will probably still stay pretty even sales wise in terms of software and systems.
Titanfall as an XBOXOne only game would have been something to brag about more but I don't see it as a big momentum changer at the moment. It will boost some sales short term but I still think XBOX won't have a dominant lead (or even any lead) in the US this time around. Maybe when Halo gets here if it releases sooner than later things could change for now though it seems unlikley...
