The New York Times caught up with Telltale Games on their ongoing projects. The most interesting part of the piece is the news that George R. R. Martin's personal assistant, Ty Corey Franck, has been assigned by HBO as a story consultant for the Game of Thrones game adaptation.
Not much to share beyond that, just nice to know that Martin's people are heavily involved with the project. As for the game itself, Telltale is keeping a tight lid on on the development. The New York Times saw some character art while on their visit, but they were just samples according to Telltale. I'm going to guess they Telltale wants to wrap up at least a season on one of their current in development games before starting public talks on another a whole new project.
