Super Mario the Hedgehog
...I've been looking forward to it.
President Iwata was discussing the new social networking features of the "Miiverse," which allows you to connect with your friends to pass along messages while gaming. He demonstrated this in-game integration of Mii messaging via a Mario side-scroller that looks a lot like the New Super Mario Bros. Mii tech demo we saw at last year's E3. Only this time the Miis weren't running and jumping alongside Mario he was alone in the action, and they popped up to pass along messages of encouragement when a rogue Koopa collided with and killed him.
The video then shifted to a map screen, displayed via the screen on the Wii U GamePad, where more messages were waiting to be read from scattered Mii characters.
One of them is saying "OK, being a flying squirrel is WAY more fun than it should be!" Could Mario be gaining a Flying Squirrel Suit in this sequel?
Another says "A baby Yoshi that balloons up to carry you? Too cute!" Again, that seems like another tease for a new and perfectly plausible gameplay element for a Mario game to include.
So could this be our first look at New Super Mario Bros. for Wii U? Last year's New Super Mario Bros. Mii was supposedly just a demo, but Nintendo has said that it serves as the inspiration for the final game that Wii U will be getting. This could very well be it, ladies and gentlemen.
I basically copied and pasted the details from IGN due to being lazy. One last tidbit I noticed was that the background of the world is reminiscent of a backround in Super Mario World:
If this game will mainly be using elements from Super Mario World, then I will die a happy man.
