Edit because I misinterpreted the post:
I don't think the NFL deal with XB1 means anything to the casual/sports gamer community (by this I mean the people who pick up game systems strictly to play the latest version of their annual sports franchises of choice.. and yes these people exist). I think with the discrepancy in PS4 vs XB1 users, the total number of madden units moved is going to favor the PS4.
