Basically, one of the main reason not to buy the first year a next gen is to be someone reasonable that waits and see to make his choice sure. Now that it's 2:1 (with a proven 3rd party support and better hardware) such buyers will massively go for a PS4 and make the gap wider. I can't see any reason for the gap to be stable, for the next buyers to reproduce exactly the same ratio than early buyers. The gap will reduce if MS does something really significant (any combination of price drop, exlusivity, campain, features), or it will significantly widen from the current 2:1.
