As far as Song of the South goes, it's an example of a big business not wanting to offend anyone and subsequently lose customers. Whatever they decide to do (or not do) with Star Wars will be based on money, PR, marketing, and things like that that businesses think about. I don't want to get my hopes up either, but remember, Star Wars is no longer controlled by a man who wants the OT to be erased from existence, so if Disney thinks it's a logical decision to release the OOT, they'll do it.
