Yeah, its definitely a marked improvement in terms of pure aesthetics.
The SSS (sub surface scattering) used on the skin, the changes made to the armour; higher resolution normal maps, changes to the lighting/shadows and overall textures makes a world of difference to the overall scene. Character models might be a technically downgraded.. but objectively speaking, I can't spot the difference between the two. So its well worth the trade off in polys imo.
Edit: Also, like that they dialed back the specular maps on the armour. Makes them look like they're actually worn pieces of equipment rather than a new chromed out metal.
