Hardcore Gamer: Lucky for skeptics, but unfortunate for Madara fans, Namco Bandai has confirmed it to be fake via YouTube. (Naruto Shippuden: Ultimate Ninja Storm 3, PS3, Xbox 360)
There is only one possible excuse they could give for not including Madara "we are saving him for the next game". Which would be a slap in the face to fans
But I'm sure we'll see him in the game. There's no way CC2 can't include him.
