What you guys still fail to realize that X1 sold only ~10 % less than the PS4 even with a bad reputation, higher price and all that.
The difference is so insignificant that a price cut can make X1 overtake the PS4 in a few months.
It's not like in Europe where PS4 sold 2 times more than Xbox, it's really close.
The mistake you are making is that you somehow have it in your head that the xbox brand=/better than the PS brand.
If you are going off how well the 360 performed in NA, and believe that there are somhow all those people waiting to buy an X1, then just look at the PS2. The PS2 sold over 150M consoles worldwide compared to the 30+M worldwide the xbox sold, yet the PS3 was decimated in NA. Better yet, just look at the Wii and then the WiiU. Brand loyalty doesn't hold anything near as much relevance as you seem to associate with it.
Honestly, I don't think the X1 is loosing to the PS4 enough in NA to not at least keep the fight close. But I also don't think its going to somehow start outselling the PS4 by over 70K each month from price drop onwards for it to one day outsell the PS4 in NA. If it would make you happy, I expect the XB1 to do very very well in june when they drop the price and settle down the months after. But don't get your hopes up that price parity is enough to turn things around. At its heart, pound for pound, the PS4 is overall better hardware you know?
