Hey, that could work, actually - although FIFA wouldn't like it probably!
To be honest, I personally do not know anyone playing FIFA who spends any significant amount of time with international teams, anyway. They are all into their clubs, leagues and Ultimate Team.
This looks more like a loss for FIFA than for EA. Definitely. Furthermore, with the Qatar World Cup coming up, FIFA does not have that much time to find a new official video game partner. It could very well play out FIFA not only not getting the billion dollar deal it wanted out of EA, but getting less than it used to in order for EA to do them the favor of developing a "DLC pack" for QWC on time!
