The problem is, we see it from more of a consumer standpoint, obviously.
When we look at it from a business standpoint, Nintendo are actually doing the best. Microsoft incurred massive losses to which they haven't recovered. The Xbox division is still billions in the red despite the success of Xbox 360 and Xbox Live. Sony also had a serious amount of loss too. Both companies consider that division a hole. There are many Microsoft insiders and analysts that want them to drop the Xbox division once and for all and it wouldn't surprise me if people in Sony didn't want the same thing.
Sure, Nintendo had two years of loss in their entire history, but they're now turning it around despite the Wii U selling horribly.
There's continually "Nintendo is doomed" threads and statements around the Internet, and I don't get it. The Wii U? Sure, that will never actually sell really well now and it may well be doomed, but the company itself? No, far far far off. Sony and Microsoft are actually in a far worse position with their gaming divisions.
