Didn't see any thread, thoughts?
Google searching the images leads to some kind of blog, where apparently they have been posted on 2012/01/17.

Bethesda says Doom 4 is not canceled.
dont forget to check out the rar file linked on that page, much more images in there (characters, zbrush assets and more ingame shots, no demons tho)
"Those images have nothing to do with what you're gonna see in Doom4. When we officially show things you'll see awesome"
