EA backed off on the "no game development" for the Wii U as the company announced they are currently working on games for the console although it won't be as many games as they are focusing for the PS4 and Xbox One.
Being rumored Disney might have forced them to make at least Star Wars games since EA is in no position to break their terms unlike with FIFA and the NFL.

According to a recent rumor, the Sega-Nintendo partnership might be a lot more deeper and an actual alliance than just a "3 game deal."
