Why are people so down on Nintendo? They are still making a lot of money and will probably be in better shape than Sony or Microsoft once the Wii U games come in.
They are also still riding on original DS sales and the 3DS is kind of booming.
If you're going to worry about someone, worry about Microsoft. (PC related sales way down, Windows Phone still not a success, Windows 8 based tablets not selling)
I mean christ, the Wii U hasn't been out that long and let's not forget the 3DS also fucking sucked when it first launched, in fact the 3DS was worse than the Vita at launch and even a few months after yet people like to rag on the Vita all the time, the 3DS was worse. I had one at launch. It was awful, the hardware was awful (build quality and design of the original 3DS stink) and so were the games, I have an XL now and am very happy with it, but don't bet against a console because the launch was rough, look at the PS3, look at the 3DS.
