Does it look like Xb1 is having a better sales launch than 360? I haven't really kept up with it, but If so, that would definitely solidify the idea that their market share is growing every generation
With Xbox always dominating North America, dominating UK, being even in Europe and Australia, I don't think Xbox needs Japan. I suspect this new gen will continue the Xbox dominance. Sorry Nintendo, you never even made it to the party.
