X1 Vs PS4: has the battle turned around ?

[Augen]

Right now in the three major regions

1. EU: Seems like Sony has significant advantage here, my guess for first 18 months? Roughly 2:1
2. NA: Sony has slight advantage, but Xbox has marketing and brand there, 18 months? Roughly 1:1
3. JP: Sony barely has to do anything here and will utterly dominate, 18 months? Roughly 10:1
