Nah brah, nah. It'll at least surpass Skyward Sword, maybe Majora's Mask and if it's absolutely groundbreaking with great reception, it could sell more than Wind Waker (which was a game that a lot of people resented at the time on an install base of 21m - still sold almost 5m). The Wii U has insane attach rates, especially with huge games like this.

Not really. Anyone who wants to play it has a Wii U. The best selling Zelda on a single platform was released on a console that sold 32 million. Both Skyward Sword and Majora's Mask required accessories, reducing their install base sizes.  And the Wii U is going to sell more than 15 million.  It isn't half way through its lifetime yet and its sold almost 9 million. It can definitely double that.

nah it should sell a lot wii U users will be starved for games by the time it's out

Zelda game sales don't necessarily seem to be influenced much by the sales of the console they are on. Ocarina of Time sold more than the Wii version of Twilight Princess and double what Skyward Sword managed, even though the Wii obviously has a MUCH larger install base than the N64.

If Zelda U looks good at E3 and continues to build hype, peaking at the time of its release with great reviews, I think it can outsell Majora's Mask and Skyward Sword. Even on Wii U, I think 4 million or more is possible. It will just depend on how well Nintendo shows it off and how good the game actually is. The fact that it's an open-world game already bodes well for it, because it shows that Nintendo is pandering to the Western audience, which has consistently been where Zelda sells best.

it won't look dated at all because it won't be dated at all.

Zelda U will sell 6m+ and wii u will sell much more than 15m.

No; it will outsell Majora's Mask.

You honestly think Wii U will sell 15m Ltd?
Next Nintendo console is coming out in 2017 at the earliest
But anyway, I think it will outsell Majora's Mask, Skyward Sword, and Wind Waker, so no

Tbf, Twilight Princess is one if not maybe the most hyped game ever. Also, I think Zelda HD got a lot of love unlike The Wind Waker and Skyward Sword. I believe that the game has a lot of hype behind it, not as Twilight Princess but not abysmal.

I also don't think a TP sequel like the demo would have worked more than another Ocarina of Time sequel. Nostalgia alone would have locked 3M early in the first months despite the installbase.

Well it could sell up to 20m but at the moment it s selling like a 15m ltd console. consoles usually peak in their 3rd year and then the decline begins. At the moment the wii u will probably reach its target of 3.6m for the fiscal year and be at around 10m. So another 5 million from march 31st 2015 onwards does seem conservative i'll admit but better to be cautious than to be brash and end up with egg on your face. For all we know the wii u could have already peaked (smash and mariokart 8 affect) and the sales could get even worse in the future we just don't know so for now i'll predict a minimum of 15m and maximum of 20m.
