It wont be a market leader, like the Wii was. It will sell probably as much as its second biggest seller console (NES at 61 millions). It can maybe move as much as the 360 and PS3 at 70millions.

I also think that it wont have a 20 million seller (except Nintendo Land or NSMBWU if they are bundle with the system)
We will se that Wii U fit will "bomb" (it wont reach 10 million)
We will see Mario Kart 8 and New Super Mario Bros U "bomb" (they wont reach 20 million, but they will probably get 15 million)
No major 3rd party support as the Wii :( (except for Japanese Developers, western devs hate Nintendo)
Smash Bros as you say wont reach 10 million ;( (but it can get 8 million probably :D)
Zelda U will be better and sell better than Skyward Sword :D ( maybe 6-8 million)

let me try!

prediction: the wii u is a success

Actually, its obivous that MS is doomed because you don't see NItendo supporters going into Sony and Microsoft forums making doomsayer posts to try and ease there feeling of impending doom.

Well, I'm basing my prediction on a couple of assumptions:

Obviously if Microsoft surprises us with a spring/summer launch, WiiU won't have amassed 15m sold by then.  And if Nintendo sells it for $599 US DOLLARZ (lol), it would obviously change the outcome.  So there's not enough confirmed info yet for me to risk, say, having a penis as my avatar. 

But assuming that it launches for $299 (or less), I say WiiU will sell at least 15m WW (according to Vgchartz data) in its first full year of availability in all three major regions (NA/Europe/Japan).

Keep in mind that 3DS did 16m in the same time frame with a botched launch, a $250 price for the first five months after its debut in Japan, and, most importantly, zero system selling games until late November.  WiiU is launching with a 2D Mario game, Nintendoland, and a veritable smorgasbord of variety in its first few months (Pikmin 3, Assassin's Creed 3, Aliens, ZombiU, Project P-100, Just Dance 4, Darksiders 2, etc).  So yeah, without shortages I think it'll get there.

Of course not but nintendo will stop making consoles for a while, see with all the money they will get plus their bank and the money in their secret underground facilities they'll buy all still operative (by that time) oil companies in the world then refuse to give oil to anyone and when the world feels the need they'll agree to re-sell the oil companies for 7 times their value, then with that money they will buy Rusia and turn it into the real life Nintendo Land, make more millions of dollars with all the visitors and finally Nintendo will buy the world then turn it into mushroom kingdom so people can live a videogame making the earth the biggest console of all time but you'll have to buy extra lifes as dlc. :)

You can smell when Nintendo is heading down?

Then may I remind you (or perhaps just 'mind' you if you haven't heard this before) that even if Nintendo has to sustain a decent loss every year from now on they would last another FIFTY years? (or maybe even more, I don't remember)

In other words, spending is not a problem at all. All they did was to overestimate the 3DS. The 2D Mario title for Wii U is only there to ensure success.

The guy from Microsoft is wrong. The U, on paper, is around 3 times more powerful than the 360. In real-world performance terms the eDRAM should push that to 4 times more powerful. You've also got to take into account Nintendo's forward thinking in using a GPGPU, which is huge news in terms of the U getting multiplatform games next gen.

I disagree with the op on so many levels I don't know where to begin.

Also forgot to mention that I agree with the poster that said that the U will have a huge head start by the time the PS4 and 720 are released. Although I'd personally guesstimate anywhere between 10 and 15m assuming that the PS4 and 720 are released around the same sort of time in 2013.

If you're not a MS fanboy then you must be some kind of Nintendo hater because you know nothing about the 720. And even though you don't know anything about it you assume it will be dominant? Oh brother...
