It will come down to MS's stubbornness to bundle kinect.
The longer they keep it bundled, the slimmer its chances become.
I bet if there wasnt kinect and they were the same price, sales would be very close. Even the resolution thing wouldnt have mattered as much as it does because of the fact that you can play the better version of multiplatforms while paying less*.
*Excluding cases where retailers have charged ridiculous prices or forced people to buy 3 games in a bundle because of PS4 shortages.
