Prediction: PS4 to outsell Xbox One by 2:1 in 2013.

2:3 ratio is more likely I think. I think it really gets down to how many units each company can produce at this point. No matter how many they manage to ship in 2013, they will likely sell out of their stock. At this point in time, it looks like Sony will be able to produce more units than MS in 2013.
