If the Wiiu can sell 3.75 million unit this year, they are still 9 million away from matching Game Cube numbers. I'm thinking the last big year for WiiU is 2016. Expect sharp decrease before it's eventually discontinued. 

**There already rumors of a new console from Nintendo in the works.

**Seem like Zelda will be the last AAA Nintendo consoles on the system release in 2016. 

**3rd party support is all but gone

**Nintendo doesn't seem keen on dropping the price, they might simply prefer to abbadon the WiiU for the next console.

Yeah, it's almost safe to say that unless something magical happen. It may hit 20million though.

Very safe thing to say. Its a shame though, its a quality console and there's a lot of fun to be had on it :(

Your right until proven otherwise.

Get ready to have this thread bumped in 5 years "if" WiiU passes Gamecube.

Boy, get ready to be OWNED in 5 years! Won't you feel silly ;P

I'm not sure why this is even a topic anymore, this has been clear to most people for quite some time now.

There's no denying this, that's for sure.

As a fan of Nintendo and Super Smash Bros, it pains me a bit to admit this, but it's the truth.

I think it was safe to say that a while ago for better or for worse. Unless Nintendo decides to keep it alive for a lot longer than anticipated, I don't see it turning around

So... do you want a medal, or...?

I actually dont think it will hit 20million.

late 2016 or early 2017 new consol release from Nintendo, they drop support for wii u.... wii u sales drop like a rock.

Yeah pretty much. Nintendo screwed the pooch royally
