I'm going to have a hard time being enthusiastic about UT2K7 if the figures are made of wax.
Ah, yes, the G.I. Joe syndrome. Really, though, I think the UT2k7 models are a lot less plastic looking than other game models. Compare them to FarCry or SC:CT and you'll get what I mean. Wax is actually very close to the opacity and texture of human skin. This is why wax is used to make human sculptures in reality. Doom 3's biggest problem was that the texture and model quality wasn't all that great up close. Normal mapping and specular lighting create an illusion of depth and detail from a distance, but up close, it doesn't look so great. From what I've seen thus far, UT2k7 doesn't have this problem.
