The Xbox One doesn't offer anything new, does it? What of the PS4? That doesn't offer anything new. An opinion doesn't or shouldn't be passed off as factual. If Nintendo went out of the console business, there would be just Sony and Microsoft but the competition wouldn't be that great, that's not how it works.
I was pointing at the fact that Nintendo released a console with pretty much no support. Sure the PS4 and XB1 don't have anything new either, but they still have 3rd party support, which does in fact sell systems. Also, as of now the competition isn't great either, the only thing Nintendo managed to do is cause both systems to develop crappy motion controls which barely any games use anyway. The Wii sold because it had the motion controls and managed to put the focus on something new and innovative, something the Wii U doesn't have.
