blu-ray double dip = bad?

[andyn1080]

so i sitting here thinking when studio's double dip or even triple dip on dvd it's never really fazed me b/c it was usually some extra crap i didnt need or a few extra minutes thay added......but now with blu-ray and it's superb video quality this double dipping or even triple might just suck for us, for instance i bought the new harry potter and the first one (Stone), now that they are re-releasing them in the coffee book thing does that mean that the video has been remastered? if so then think about it, every time they "dip" they might sell it as a "remastered version" meaning we will all want it b/c it will look better, which basically sucks b/c we will be buying the same movie over and over b/c it will look better.............
do you think this will happen?

is this happening with the potter films?

if and when it happens will you re-buy the movie?
