If Xbox One is only 1.4:1 behind ps4 now, is because of launch and christmas sales. We need to remember Sony spent all the last generation being far better than Microsoft during January-October, and Microsoft being better during christmas except a few years...Even this year Xbox 360 beat PS3 one week during christmas when it was selling a lot less the rest of the year.
I'm sure, after the "champagne effect" of both launches, PS4 will start selling 2:1 or 3:1 during each week during the "boring" months of the year....
