Will Lucas correct the colors for the blu-ray release? Well, if history is any indication, I'd say it's more likely that they'll be even more screwed up than the DVD release.
Also, don't be shocked if the Han / Greedo shootout gets altered yet again. This time, Greedo shoots first and misses, Han shoots second and misses, then they shoot virtually simultaneously, with Han hitting and Greedo missing.
Or, better yet, maybe they'll CG in Greedo suddenly having compassion on Han, getting up from the table, and walking away. See? He learned his lesson from the fistfight with lil' Ani in Episode I, and so he no longer needs to resort to Bullying. Isn't it fun to give peace a chance?
