Has Larian mentioned anything about having raytraced lighting? While reflections might be cool one couple shiny platemails, I think where it would really make difference are contact shadows and global illumination. In this kind of sandboxy and dynamic game, you can't bake the lighting into the textures. Having proper shadows and illumination from torches, spells, movable objects etc. would really bring the graphics to next level. It'd give the graphics more depth and less fake gamey look that many have complained about (i.e. too bright, not bg1/2 like).
Next gen consoles, Nvidia graphics cards for 2 years and new AMD cards this year all support raytracing on hardware level, so it'd be a shame if was left unused.
