Why does Watch Dogs help PS4 but do nothing for XB1

[Aerys]

I wonder if COD One bundle with free game will sell more than COD PS4 at full price.

Since Fifa One bundle has been outsold by a huge margin by Fifa on PS4, it's a legitimate question.

I think people are more and more bored by COD though, and Sony has been damn smart to lock the next big FPS + the next big open world of the generation like they did for assassin's creed, now people will always think Watch Dogs = PS4. With  these 2 clever moves, it is very unlikely that microsoft will  take back Uk or Us.
