Evidently EA doesn't agree with themselves, because they continued publishing Madden and FIFA on Wii through the 2013 editions, despite it being a dead system by then. And surely made some kind of profit, since FIFA 2013 was literally just a reskin of the previous Wii version, and still sold almost half a million copies.
I would say Wii was an easy port? Or they saw the sales declining trend?
Wii U they need to consider the nintendo's IPAD?
