Basically all placeables and creatures in NWN2 will be scaleable. This essentially eliminates the need for various larger and smaller models, which gives the builder a lot more options. Also, most things in the game will be colour-customisable in varying degrees. Apparently the degree of customisability depends on the modeller, but many things in the game will have two or three customisable colours.
