Ubisoft has announced a new released date for South Park: The Stick of Truth, with the game now down for March 7, 2014. The following statement was released by Matt Stone and Trey Parker (presumably they spoke in tandem) via Ubisoft:
"We always wanted the game to feel like you're actually in an episode of South Park. Getting the game up to the crappy standards of the show has been a real challenge and we're excited to say it's taken way longer than we thought it would."
To offer some form of consolation, a gameplay trailer featuring action from the Giggling Donkey section of the game (that was featured in this preview) has been released.
