Then you disagree with what skyjedi said. He said that the Blu-Ray will be the 2004 master, but at a higher bitrate, which would mean it would have less compression issues than the HD broadcasts do. That's common sense. Yes, it will be better than the 2004 HD broadcasts simply because it won't be compressed as much.

That does not mean the colors or audio will be fixed.

And I would be absolutely shocked if they do new HD masters - it would mean they'd have to re-do all the new CG work they did for the 2004 master. I highly doubt they'll do that.
