Nintendo recently stated during an Iwata Asks interview that Pikmin 3 was coming out in Spring 2013. Turns out they made a mistake.
Yes the game is coming out during Spring 2013,…in Japan.
“Pikmin 3 is scheduled for release for the Wii U console in the spring of 2013 in Japan, and during the Wii U launch window, from system release thru 3/31/2013 in the US. (Editor’s note 10/19/2012: We originally published the article citing only the expected release timing in Japan. We apologize for any confusion this may have caused.)”
Nintendo is now saying that Pikmin 3 will release in North America before the end of the Wii U launch window. Meaning the latest it will arrive is March. Great news to hear, as a Spring release date could have meant as far back as June.
