At the end of the 8th Gen I think it'll be around 82 million, so in the 80-89 range.

I don't see it catching Wii numbers, as a lot of the casual crowd and the 'impulse buys' will be lost to Nintendo. I don't see it fail either, because Nintendo fans alone secure like 40-50 million sales, and I think it'll be able to sway some of the PS360 crowd too.

As a Nintendo fan myself, of course I hope it'll be stellar and sells like 200 million, but realistically that's never going to happen :P.

80mil

between 50-60m
is going to be a moderate success, but i dont expect big numbers, depends on when the new Ps4/Xbox are released and their price
the WiiU is going to struggle in Europe, but in Japan and America is going to do well...

Nintendo fans alone did not secure 40-50 million sales for Gamecube.  This isn't a knock on Gamecube by the way.  I owned one and enjoyed playing games on it.  I just had to point out the wrongness in that statement.  Personally, I chose 60-69 million as what I thought was a conservative estimate for Wii U.  Yes, they will lose the "casual"/motion-craze gamer, but I still have high hopes for the system and it's new controller screen innovation, and intend to own one as well.

exceptionally well 70 million at least

Worst case scenario, just above the original Xbox sales. There's at least 4, maybe 5 million more people Nintendo convinced to purchase their monstrosity of aconsole beyond that of regular Nintendo sheep who bought the purple lunchbox. Add onto it another cool 2 mil for the Wii Fit crowd

Was going to vote for 60-69 but changed my mind at the last minute to 70-79.

It's a Nintendo console launching with a 2D Mario game so it's going to have strong sales right at the start with the likes of Wii Fit U, Wii SPorts U, SSB U, Mario Kart U, hopefully another Metroid FPA, at least one Zelda and a 3D Mario during the next few years to keep sales momentum going.

It's going to sell like hotcakes imo, I'm surprised it isn't getting the likes of Bioshock Infinite, Tomb Raider and GTA V tbh. It does have a good launch and launch window line up from third parties but I was expecting more tbh.

55 million.

I believe next gen total sales will be smaller than this gen and I believe Nintendo will lose significant marketshare and the Wii U will have a shorter life on the market than PS4 and X720.

PS4 - 100 mill in 8 years until the PS5 comes out
X720 - 90 mill in 8 years
Wii U - 55 mill in 6 years

1. The "Wii" brand won't help much here - why? Because the casuals liked the Wii for its motion sensing and ease of use. They bought the Wii to play Wii Sports, Wii Fit, etc. etc. Casuals have pretty much forgotten the Wii, when they hear about the Wii U they will be like "is that an accessory for that Wii thing we bought and threw in the attic a few years ago honey?" which leads me to my second point.

2. The fact is Nintendo has lost momentum. I don't see the hype of a new Zelda or even Smash Bros. reaching what they did with Twilight Princess and Brawl. Skyward Sword fell flat on its face (not many people cared about it) and a new Smash Bros. seems like more of the same.

There just isn't any hype about the Wii U. It's like... whatever. The Wii started off hot and continued its streak for YEARS. The hype for the Wii was MASSIVE.

After E3 2006 people were giving the Wii pretty much every award they could give it. People wanted it. The media was hyped up. On the other hand.... the Wii U has had NEGATIVE reaction, the media is giving it NEGATIVE press if any, and no one seems to care. Oh Nintendo Land whoopdy doo, won't have NEAR the effect Wii Sports had for the Wii.

3. Depends on price too. Which is unknown as of now but from what I have seen anything over $250 and it's not worth it. This controller will not give people a reason to spend $100 more on last gen technology.

4. Nintendo franchises guarantee at least 20 million sales.

So I will say this will sell 40 million at the most.

It's not wrong per se, the Gamecube era was the Playstation 2 era. PS2 was so dominant, nearly everyone went there. Even Nintendo fans. It wager a lot of them came back (or new people became fans) for Wii and DS this Gen.
