I really dont think this would ever happen. Of course I would love for it to happen as I can't stand EA. I will say that if Microsoft wanted to lay the smack down on sony they would do this. You make Madden, Fifa, mass effect, drago age, anthem... xbox only and you win. Microsoft has the pockets to do it.
Yea I don't think they are in too much trouble. Mass effect andromeda while it did have some animation issues in the beginning, the core gameplay was very good. The game suffered a lot from the ME3 ending fiasco. Dragon age inquisition was very good and very well received. I'll be curious how Anthem turns out. Even if its not that great I would be very surprised if they shut it down. EA specifically bought them to have an RPG studio.
