Silly question to ever ask. It was known before this generation ever started that the Wii U would be 3rd. Only question has ever been was how far behind the Wii U will end up at the end of the generation. Nintendo went the route of trying to create a fad like they successfully did with the Wii and reaching like that rarely succeeds. Even with the Wii we saw how it was a huge initial success then tanked as the generation continued.
Its libraries that sell systems not a single game.
