Unless it's bundled on XOne, this game will bomb in total sales. The competition is tough this holiday, and it coming out a year later on PS4, be it at $40 or $60, it wont sell like it would have if it was a simultaneous release. If it's $40, then it's less revenue on a major platform for its release.
