Well, it WAS suppose to come out December 10th, but it looks like South Park: The Stick of Truth won't make it out this year.
Ubisoft has on their blog the new "official" date is March 4, 2014. The thought they had it easy on publishing the once THQ title. Turns out they had to go back and redo the game.
Ubisoft's having some delay problems going on lately with Watch Dogs and The Crew also being pushed back. Stick of Truth seems to be in a constant delay though, but I guess in the end all we want is a good quality game and if this is what it takes, this is what it takes.
