Far be it from me to defend EA, but they do have a point this time.
Nintendo went for the same strategy of pushing some new "disruption" in the Gamepad instead of competing on specs. They were expecting to have another Wii on their hands; even projected initial sales were in the same ballpark as the Wii's launch. Instead, as the article pointed out, there are people who don't even know the WiiU is a separate console, and think the Gamepad is just a Wii add-on. This despite the fact that the WiiU was first announced in 2011 and is the first next-gen console on the market. If that doesn't scream marketing faliure on Nintendo's part I don't know what does.
So you have a device selling like crap, that is so underpowered compared to the next gen consoles that it's competing with current gen consoles with much bigger install bases as well. Even Nintendo isn't doing anything special with the Gamepad in most of it's upcoming titles. Why is any third-party publisher required to help turn the situation around? It's Nintendo's fault for not offering a compelling platform that people would want to buy--and devs could put their newest titles on--in the first place.
At this point, it's looking like sticking with motion controls and putting out something slightly less powerful than the Xone would've been a much better bet. They could've just sold the Gamepad as a separate add-on for people who wanted off-TV play. It's on Nintendo to prove otherwise, and no one else.
