Except that whole 'great games sell systems' is rubbish. Hype sells systems, and the Wii U has none going for it. Games like Mario, Zelda and so forth will shift a few consoles to pre-existing Nintendo fans, but for the mass audience desperately needed to sell consoles, they want the games that everyone is talking about (GTA, Last Of Us, Halo, etc) on a console their friends own and consider cool. Nintendo's franchises have long ceased to generate excitement outside the company's established fanbase, apart from certain broader titles like Mario Kart. If Nintendo want the Wii U to take off, they need something which will surprise and amaze people within a popular genre IN ADDITION to advertising the console by telling people the reason it's better than the competition rather than constantly playing catch-up on the whole 'just to let you know, this is actually a new console' thing (itself a mess of Nintendo's own making).
