In case you doubted this is The Walking Dead, Gary Whitta RT'd it.

"I can tell you what you already know, which is season two is coming. Theres not much to say because it really is very early its a way off," said (Gary) Whitta. "But, knowing that its 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. We may have a little something extra for you between season one and two. Whitta continued to tease that something is in the works right now that will make the wait for season two slightly less agonizing.
A short mini-episode to introduce new cast members maybe? Shit, I'm hyped.
