The title is confirmed to be an updated version of last year's New Super Mario Bros. Mii.
UPDATE: It has been confirmed that the title set to be shown at E3 is none other than an updated version of New Super Mario Bros. Mii, which was seen at last year's E3. Yesterday's story (posted on 04/16/2012 at 5:29:50 PM) can be found below.
The title Miyamoto excitedly revealed years ago during a round table will finally be seen by the public.
Yesterday, we reported that Nintendo would be showing off a new Mario title for its soon-to-be-released Wii U console at E3. However, it appears that Shigeru Miyamoto also let slip that a Pikmin game would be at E3 in the same interview with Spanish newspaper, El Mundo. Again, the details were questionable, but Nintendo has issued the following statement to address concerns:
However, Wired magazine is saying otherwise.
LATEST UPDATE: Wired magazine is defending its reporting of Miyamoto stating he's stepping down, in a statement to G4. Some, including Nintendo, are claiming that this was due to a misunderstanding, perhaps due to a translation error, since Miyamoto spoke in his native Japanese. However, Wired editor Chris Kohler says that the translator was Nintendo's own. “It was Mr. [Yasuhiro] Minagawa; who has been Miyamoto’s translator for a very, very, very long time,” Kohler said. “I did an interview with Miyamoto in 2002, and Mr. Minagawa was Miyamoto’s translator then. It is Nintendo’s translator, not ours.”
