After several screenshot where leaked yesterday thief has been announced by Eidos Montreal.
The reboot of the classic stealth series has been revealed.
It will see the return of series lead Garrett as he explores a steampunk metropolis known as the City, a place ruled by a tyrant named the Baron.
Eidos Montreal was the team behind the critically-acclaimed Deus Ex: Human Revolution.
Thief will be available on PS4, PC and other next generation platforms, suggesting a release on the new Xbox.
"We're handling a precious gemstone with Thief," said Eidos Montreal general manager Stephane D'Astous.
"Fans remember the original games very fondly and we want to preserve that essence - which we have excellent experience of doing at Eidos-Montreal - whilst also introducing Thief to a brand new, next-generation, audience.
"Our goal is to deliver the fantasy of being Garrett, THE master thief, and we're building this game around that core experience."
Thief 4 was informally announced by Eidos in early 2009, saying it would "break new ground" with the franchise.
It was then rumored to be shown at the Game Developer Conference in 2011.
The franchise debuted in 1998 on PC with Thief: The Dark Project. Latest title Thief: Deadly Shadows saw a release on the original Xbox and PC in 2004.
