There´s this rumor Nintendo will release Wind Waker/Wii U bundles, but I wonder if it wouldn´t be much better for them to have a NSMBU bundle..since the Wii U´s launch, the game has had a very high attach rate, which shows people are buying the system to get to the game.

I´m not sure Wind Waker is gonna do something substantial for the system, probably not, and it would seem Nintendo might be more interested in pushing Wind Waker than the system itself.

What´s your opinion?

You're completely right, aI've just stated it in a different thread. Mario Bros U + NintendoLand (and a small price cut I would add) would finally make the system look attractive. Also you're right about the second part, Wind Waker isn't going to change anything.

Appeals to a different audience, I guess. Link is hardcore.

This might get new people to try out Zelda though. NSMBU will probably sell no matter what, but Zelda games have never had the sales Mario has (well, what series has, really). Maybe Nintendo just wants to try and increase awareness of the series a bit more.

Because Nintendo wants NSMBU to sell for a while longer at a full $59.99 retail price. They probably aren't happy with its level of sales right now. They spent (apparently) three years working on it, lol, and it's by far the lowest selling 2D Mario ever.

Zelda: WW from a resource standpoint is a nothing project from Nintendo. They bumped an ancient GameCube game's resolution to 1080p and added bloom lighting ... gifting that game away for free costs them practically nothing. It's the perfect "extra" game to throw into a Wii U bundle.

Probably because NSMBU is still selling well and it's lifetime sales will be much higher than Wind Waker's. I guess they feel like they can make more money this way.

People that buy Wind Waker HD bundle will most likely buy NSMBU during wiiu lifetime, not the other way around

They want it to sell out and once they are all gone this happens.

it is not the right time. Holiday will be cool just by the time Super Mario 3D World comes out. That would be a kicking ass time.

Because NSMBU is the best selling game on the system and they will lost money by giving it away
