Nintendo's highly anticipated real-time strategy game Pikmin 3 is scheduled to release for the Wii U in spring of 2013, Nintendo confirmed in the latest Iwata Asks Q&A.
Nintendo has already announced plans to release Pikmin 3 during the launch window of the Wii U, which has been defined as the period between the system's release on November 18, 2012 and March 31, 2013. With spring technically beginning on March 20, 2013 (assuming we go by the actual date), you can expect to see Pikmin 3 hit store shelves on Tuesday, March 26, 2013 and three days later in the UK.
Keep in mind, that date is nothing more than speculation. The Wii U is set to release on November 18 here in the U.S. with two packages: the 8GB Basic system and the 32GB Deluxe system.
