A whole bunch of images (presumably from a Game Informer article) of Thief (previously known as Thief 4) from Eidos Montreal have reached the internet. You can most likely look forward to a proper announcement with full quality images and official quotes in the very near future.
As we don't really like to carry images of questionable origin you'll have to make your way over to NeoGAF for a closer look at what appears to be scanned images.
Update: The images have been removed from NeoGAF, but can still be found here.
Update 2: Game Informer have now published the official "online version" of the story/announcement.
