. . . or at least the name is. Polygon reports TTG has been acquired by LCG Entertainment, and that, and I quote, "some of Telltale’s back catalog and will work on new games based on a few Telltale-associated properties, as well as new licenses." The Wolf Among Us, Batman, and Puzzle Agent are part of the roster.
We know some other assets have sailed off -- The Walking Dead for example -- and while there are murmurs of former employees coming back in some form or other, it's uncertain how Telltale-y this new Telltale will be. We shall see.
