Well, this thread shouldnt go to waste: http://www.gamestar.de/spiele/the-elder-scrolls-5-skyrim/news/the_elder_scrolls_5_skyrim,45309,2320882.html there are some more screens, previously only seen in magazines.
The first picture on the slide show, if you look closely, Chuck Norris is standing behind the counted on the left, though it appears he has grown his hair a little longer, and his beard a little thicker.
When Chuck Norris stands in your picture, you know that either you will be very successful, or you a very stupid for believing that Chuck Norris is as amazing as the internet makes him out to be.
Detailed
Back on subject.... If you look closely, it appears that interiors look much, much better. Exteriors don't appear to have gained that, but much more appears possible than in Oblivion and the draw distances are much farther and convincing. It looks like they have kept their concept from Oblivion where you have multiple landscape textures, with two versions of each, a grass and non-grass version. What this means is that most grass probably does not have the greatest quality. For the grass to look realistic, they must add the individual meshes by hand, or make a much better system for placing them which would likely be much more taxing on the systems. In basic terms: the grass has to look like it does so as to not kill your xbox and/or Ps3 and/or PC. The textures appear to be much more detailed than those found in Oblivion, but from the looks of these pictures, the self shadowing on characters and and landscapes look blurry. This is because the shadows do not allow for good screenshots. The shadows in-game are always moving, or at least that is what I understood from the gameinformer articles, which means that it is hard to make the shadow and the texture underneath the shadow look good in a screenshot. Because of this,I assure you all that either the game will look much better in video form, or it will look much worse. If you look at image 3 of 11, on the right, there is a moss covered rock that looks extremely blurred. This is an example of what I was just talking about. The clashing of the texture and the shadow does not allow for good screenshots... Another thing that is somewhat obvious if you are looking closely enough is that textures at a medium distance look amazing, while things up close and far away look blurred. Also, static (non-moving) objects appear to look much, much better while moving textures (shadows, the arm in the picture in which the character is fighting what appears to be a lycanthrope (were-creature), and anything with an animation in general) look blurred. Some of this blurring can probably be attributed to motion blur, a much wanted addition (as can be seen in the Oblivion modding community).
Simplified
Interiors > Exteriors
Movement on screen caused motion blur (like taking a picture of someone who is moving) which makes the screenshots look worse
The game will either look much better or much worse in video form
Some things such as grass are simplified and not placed by hand so as to not kill your console or PC.
Edit: Oh and if these are Xbox screens, expect the PC version to look 4X better on maximum settings and about 6X better after the modding community is done with it.
