Commence rumor mongering! According to the October 2011 issue of Official Xbox Magazine: "Look for the Fable cycle to continue with a proper, controller-based Fable IV in 2013 , says The Ball." Now, it's only a rumor, and a meager one at that, but seeing as how we're all currently so enamored with the upcoming Fable: The Journey, further news might be too much for our little hearts to handle. (Sarcasm)
Thankee much to Loud Mouthed Gamers.
