I don't see the problem. Even if a spiritual successor is released on the Xbox One simultaneously, the title (like Final Fantasy 0) will be a PS4 system seller. It'd be incredibly cheap for Sony to get another exclusive with the current sales split. Even in the US RPG's/niche titles dominate on the PS4 where both systems are competitive.
In short. Would it really matter? No.
