The writing was all over the wall, so Telltale Games released it early: We are getting sequels to Batman and The Wolf Among Us in 2018. It appears as if Telltale was going to have some big announcements for San Diego Comic-Con, but the word of what was happening was pretty much speculated and informally leaked online anyway, so it appears the company decided to beat everyone to the punch this morning with a formal update on YouTube.
The video below focuses primarily on the sequel to the next Batman title from Telltale Games for the first part of the video, this one titled The Enemy Within which is out on August 8, 2017. They then move onto the next chapter of The Walking Dead series, which in a shocking twist will be the final season for the game and bring Clementine's story to a close. But at the end of the video, members of the dev team read tweets and letters from fans asking for a proper sequel to The Wolf Among Us, to which they confirmed the news that we'll be getting the game next year.
Adam Harrington, the voice of Bigby, summed it up nicely at the end. Now we have to patiently wait an extra few days to see if anything new will be released at SDCC.
