Thief is a cult-classic series of stealth video games that has spawned four titles since the original's release in 1998. The most recent game in the series, developed by Eidos Montréal, was published in 2014 by Square Enix, simply titled Thief. It received a rather mixed response from critics and gamers alike, and currently sports a 6/10 rating on Steam.
However, despite the mediocre reception, it appears that another Thief game may be in the works.
Nearly three years ago, it was reported that a movie based on the franchise was being developed, but little has been revealed since then. Now, a description on the website of the production company responsible for the Hollywood adaptation, casually points out that a "fifth sequel [of the game] is currently in development". The full listing notes that:
Thief is an action epic poised to be the next great multi-platform franchise.
Originally released in 1998 by Eidos Interactive (Deus Ex) and distributed by Square Enix (Tomb Raider, Final Fantasy), the Thief series has spanned over fifteen years and four sequels continually retaining loyal audiences and attracting new fans with each iteration. Widely considered to be one of the greatest games ever created, a fifth sequel is currently in development to be released in step with this motion picture adaptation.
Steeped in the steam-punk world created by the video game, the film will tell a new chapter in the storied world of the series’ hero.
This piece of news is out of the blue keeping in view that Eidos Montréal executive Nick Cantin stated that a sequel would be considered depending on the reception of Thief, which hasn't exactly been positive. That said, Square Enix hasn't announced any release information for the upcoming Thief game itself, saying that it has nothing to announce "at this time".
