Will Nintendo's Wii U Fail?

Recently since E3 there has been a number of opinions on the Wii U whether it will do well or if it will in fact fail. First of all let me state the Wii U is the first home platform from this eighth generation of gaming, IMHO Microsoft's and Sony's next generation consoles will not hurt the Wii U. Nintendo is generally Nintendo's downfall, this has been proven by sells of the first Wii console which sold as of January 12 2012 94 million units worldwide, what hurt Nintendo was third party support or the lack of third party developers making games for the system. The Wii was geared to a more casual gamer to get people who never picked up a joystick or a controller to do such with games like Wii Sports, Wii Sports Resort, Wii Fit etc......which actually got Older people and non-gamers to game. It seems though Nintendo forgot about the hardcore although there are some hardcore titles on the Wii like Zelda Twilight Princess. With the Wii U if Nintendo can get the hardcore audience with true hardcore titles and continue to cater to that casual audience that bought and played Wii the Wii U will be a success.
