The reason for redesign was actually for reformatting. (Fitting the character into PS3/Xbox 360 format). It's because of how the graphics have gone further and evolve on the next gen consoles, making creatures and humans more realistic. What your seeing there is a in game cutscene (a scene using game engine) in contrast to the other picture which is a High-Res cutscene which makes things cinnamatic and more detailed. Most games lately don't have High-Res cutscenes anymore because of how well the graphics are already.
