This article is 100% right. Wii U can't save Nintendo. Cant save something that doesn't need saved.
Apparently these guys don't remember Nintendo being successful with a third place Gamecube.
People will buy Nintendo games by the truckloads and Nintendo can easily survive on them alone. I don't think they are content with just surviving, but if they wanted to go 64 dream team again, they very well could. It may not produce a mainstream billion selling console, but they will profit just like they have with all their systems('cept maybe virtual boy, but i don't know.)
I'm not saying Nintendo can't fail, that would be dumb. Just as dumb as saying the Wii U has to somehow save Nintendo.
