A purported video of Thief 4 surfaced on the Internet showing a quick 30-second clip of some CG action.

The video was originally uploaded by lighting and compositing artist Eric Wong, but has since been removed. Not much has been revealed for Thief 4, and Square Enix hasn't talked about the title publicly for quite some time. The game is still under development at Eidos Montreal.
