According to several vacancies, the studio is looking for a lead programmer and a lead game designer. The site also says that Deck Nine is hiring people to work on an unannounced AAA single-player adventure game with a focus on storytelling. Many fans of Life is Strange have already expressed hope that the studio is preparing a new part of the series.
There's no official word yet on specific plans for a sequel to Life is Strange, but earlier this year, the creators of the Don't Nod series hinted at new projects. At the same time, it is possible that the next Life Is Strange (and franchise) will be dealt with by Deck Nine in the future.
