Melissa Hutchison, who provided the voice for Clementine in The Walking Dead as well as characters in other Telltale releases like Puzzle Agent, Back to the Future, and The Wolf Among Us, has written a sad farewell to the studio that recently confirmed a majority closure. She writes, "I, unfortunately, like most of you, do not have the details on how this all came to be and I also do not know the fate of the final season of TWD. To my knowledge, they will release Episode 2 and then that will be it."

This lines up with US Gamer's reporting. "Our sources say The Walking Dead Final Season is set to end after the second episode launches next week", they wrote.
