A trailer for the next Thief game has “leaked” on to the internet, mostly focusing on giving a story feel to it. A part of it could be gameplay, namely the door opening to reveal a room full of birds in cages, but who can tell anymore with the power the next gen will have?
Almost all of the trailer stays pinned to the idea of stealth, making sure to have almost all of it stay away from combat. There is a little part where a guard does attempt to fight Garrett, but instead of entering combat Garrett dodges and escapes the scene.
A lot of people will be comparing this to Dishonored and you can definitely put the two side by side to show how similar in style they are, but remember that the Thief series came first.
Thief will be releasing on PC, PS4 and other next gen consoles (so, basically, whatever Microsoft name their next machine).
