The Siberia Blu-ray release is today. HI-DEF NINJA has posted their review. They have said the following about the video quality.
The video is a 1080p AVC presentation with a digital look to it. It’s the way that the video looks with the majority of it have a clean finish. As for the film temperature, you have your choice between the cooler tones to really bring home that cold, Russian tundra and the warm shots that are indoors. It is a mixed bag of images grit levels when out in the woods or the country to clean in the bars / restaurants. The details are incredibly sharp and this is apparent in practically every shot.
