Square Enix is apparently revealing an unannounced Wii U game at PAX East which takes place from March 22nd to March 24th. The publisher mentioned that they were showing off an unannounced Wii U game in an invite they sent out to press publications. Australian developer Straight Right has been rumoured to be working on a Square Enix port of Deus Ex: Human Revolution, so perhaps it is that.
