There are two things in particular we truly hope will be discarded in the revisions of the Star Wars universe... The Sith tendency towards Speciesism and suppression of females. Neither one of those make sense when linked with the morals Sith build upon. 

All they do is make Sith look more "evil", when Sith aren't about being evil against others' good. They're about the ends justifying the means and having to obey all sorts of long lists of rules. Independence, really.
