It has been teasing the content over the past week with the release of clips featuring photos pinned on a 'Missing' board, and with E3 kicking off next week we wouldn't be surprised to hear an official announcement imminently.
"You won't have to wait for season two to play more Walking Dead," Telltale Games writer Gary Whitta said in February. "I can tell you what you already know, which is season two is coming. There's not much to say because it really is very early, it's a way off.
"But, knowing that it's a way off, and knowing that people are hungry for more walking Dead, there may very well be more Walking Dead from Telltale before season two," he added. "We may have a little something extra for you between season one and two."
Telltale is also working on The Wolf Among Us, an adaptation of the Fables comic series.
