The thing I think IGN is forgetting here is that it isn't a question whether or not Nintendo is going out of business. I don't think anyone, even the biggest of trolls, think that is possible. The real issue is if they will become a third party company like Sega did more than ten years ago. That is a choice that has nothing to do with how much money Nintendo makes or loses, it is completely dependent upon their own decisions and the decisions of their shareholders.
Sure, the Wii U might make a small profit, whatever. However, the console is in such shambles everywhere else...next to no third party support, a complete lack of software, seemingly no movement in the online front, and not one single killer app - that there's far more issues that stockholders face than "how much money does it make." Nintendo's shareholders sure as hell don't work for Nintendo, they work for themselves, and they want to know how to maximize their investment. If they decide going third party is the best route for the company, they have the right to vote for that. And if Iwata blocks it, they can remove him as well. The fact is there's little point for the company to continue to make home gaming consoles if the only audience they can sell to is Nintendo fanboys.
