This is not the upcoming 3D Adventure for Mario, it's a sequel to 3DLand, nothing more.

So that means another mainstream Mario will come? Did Nintendo confirm this?

It can't be more obvious, between Galaxy 1 and 2 there was a NSMB. Did anyone think that was the end of 3D mario on the Wii?

This is a game that doesn't require the level of resources that a game like Galaxy does. No orchestra, meh graphics.

It's a game for fun and sales and will fulfill its purpose. It's not Galaxy, nor its successor in any way.

I don't need a source to tell you that much. The quote from Iwata in question

“Take The Legend of Zelda franchise, for example, the fans must be looking for the graphic representations that they do not see as cheap at all when the title is released for the Wii U. When it is necessary, we do not hesitate to role out our resources.”

I'm pretty sure a proper 3D Mario adventure adheres to this principle as well.

NSMB is already on the Wii U.

Damn, I wish I could be as optomistic as you, but I've lost all hope after what I just saw.

It's so clear though to me. It's so easy for them to make a game like 3DWorld, they obviously are injecting much more resources in a proper successor to Super Mario Galaxy, it just can't be more obvious to me personally.

I've been waiting (im)patiently for Nintendo's internal teams to show off something that can even compete with last gen in graphics and scope, but they continue to disappoint(outside of MK). They've had plenty of time. I mean, they haven't made a significant game release in nearly 3 years! It almost seems like they don't have the resources to make AAA titles, or something. I'm fully expecting the next Zelda to look like an HD Skyward Sword, at this point.
