The 21 minute gameplay video had better graphics than that and it was confirmed that it was the PC version. There were tons of bumpmaps, parallax maps, highres textures etc. The PC screenshots on their website are beautiful too. Why would they spoil the public with such pretty graphics and the retail product only to look like on that russian site? That would be downright dumb and almost a scam. I donīt think Beth. is pulling this.
Who knows, maybe its the Xbox version when capped at 60fps.
