There will probably be a way to buy the extras discs separately, like there was with the bonus disc from 2004.

For a long time, you could find it for $3 on amazon.

And in those screencaps in the previous page. I have to say the color has significantly been corrected back to how it should look. It still looks too dark in some scenes and some details such as shadows on people's faces still look too pronounced. But it doesn't look over the top flat out wrong.

Can't say that the color is tinted properly everywhere. Hoth still looks too blue. But it's far more reasonable and not so extreme.
