When Fox was about to release their second AVP film, one of the directors mentioned that released footage is approved of up to 3 months in advance. It's rare to find footage that's rushed into a cut. Thus, what we see early on is what things looked like 3 months beforehand. The same goes over here. I doubt that the shots where Hulk looks unpolished will survive to the final cut, as odds are they were dealt with some time ago. By now, I expect that the final cut is already done or pretty close to being done.
