The remastered books are hideous the preview i saw for empire strikes back even has a terrible cover with the 2004 Emperor.
Unless they digitally painted in the new emperor i think the book is the same.
The recoloring will be terrible though.
I think except for ROTJ dark horse hired digital chameleon to redo the colors closer to the original books.
In the much more expensive collected editions from Marvel they are available.
Marvel/disney is reprinting the whole series though if you want just the movie collections its going to be the bad new versions.
