GameStop has posted a May 2014 release date for Bayonetta 2.  As with a lot of unreleased games, this could just be a placeholder until an official release date is announced.  It would be beneficial for Nintendo and the Wii U if more ‘known’ Wii U titles released in early 2014 along with Mario Kart in the spring to help keep sales up until summer.  We could hear about release dates for more games due out in spring or Q1 2014 in the next Nintendo Direct but until then we can only hope that there is more consistent software support for Wii U beginning next year.
