Nintendo detractors have to understand that last gen the Wii sold more than 100,000,000 units and Nintendo was very profitable. Sony and Microsoft can't even come close to saying the same. Nintendo is actually the only one still making money right now.
Nintendo made a billion dollars last year in 3DS software/hardware sales. It started out really slowly as well, but when it hit the content to price sweet spot things turned around. I don't know if WiiU stands a chance of selling the most systems or not, but you'll go broke betting against Nintendo. WiiU will be fine.
Reggie told the Dorito pope on GTTV that Nintedo wouldn't make the same marketing mistakes in 2014 that they made in 2013 and promised constant advertisements and marketing, admitting that the lack of marketing was a mistake. He also boldly predicted the that three Ninty exclusives, the U versions of Smash, Kart, and Mario 3D World; will all be top ten sellers of all systems despite being on only one system. That's a bold claim.
He has a point before the PS4 and Xbone console gamers would go on and on about it all about the games, yet anymore every console argument is about the hardware and the games are only used for graphical comparisons.
