What's with all this negativity?
Even if Nintendo lost 250 Million dollars every year, they would be able to substain until 2052. They have that much money from their business.
The Wii U is far from a failure. It just simply has not picked up as quickly as Nintendo wanted it to. The media are blowing it up like it's going to be the next virtual boy. It's just like with plane crashes where the media is all over it due to the rarity of it. So yeah, Nintendo rarely has this happen.
The system is awesome though. The gamepad is very innovative, the storage is much bigger than the Wii's storage, there is a social network called Miiverse on there, and HD quality for games. Plus you don't have to pay handsome amounts of money for controllers and stuff since they reuse the Wiimotes.
The 1st party games are far from the problem as well. I mean, Super Mario 3D World getting famed as one of the best Mario games in years, the release of Pikmin 3 that many fans have been hoping for for countless years, and Donkey Kong Country Tropical Freeze being a very high ranked game.
Again, the main issue I see is the support of games on the system. I don't think Nintendo really got enough attention yet as they did with the Wii since many of their games are not the "big" ones. I mean, when the Wii came out, we had a new Zelda pushing the sales on the console, a new Mario 3D Platformer (Galaxy) that was coming out shortly, the hype from Smash Bros. that was going to originally come up in 2007, and plenty of new games like Wii Fit, Wii Sports, Wii Play, etc.
I have no doubt that Mario Kart 8 will push the sales, Super Smash Bros. for Wii U will drastically push the sales, and - depending on if they go with a Zelda that rallied the fans like Twilight Princess - continue to push the sales on the Wii U.
And I'm 99.9% confident that in 2016 they'll still be pushing the system. I don't think another console will come out into maybe 2017 or 2018.
