Umm...no. No, they won't.
It strikes me as pretty strange how you get all worked up over OT fans just assuming that the blu-ray set won't magically have "fixed" colors. But aren't you committing the exact same offence? How is assuming that they will be fixed any phenomenologically or substantially different from assuming that they won't be fixed?
The only difference is that the latter is based on observable trends, carefully reasoned logic, and actual screenshots, whereas the former is based solely on wishful (or wishy-washy) thinking.
