Those proposed changes were among my few nit-picks with the original release as well, so I'm happy to hear that they may be getting addressed. My only other suggestion would be to restore Obi-Wan's and Vader's confrontation aboard the Death Star, such that Vader's sabre is already lit when Obi-Wan meets him. In Revisited, Obi-Wan is the first to ignite his sabre, and I always thought that that had a significant (and unwelcome) narrative effect; it appears that Obi-Wan is not acting defensively, but rather offensively, which seems to go against both his and, later in Empire, Yoda's instructions about using the Force for knowledge and defence, never for attack. And likewise, by being aggressive and very much on the hunt for Obi-Wan here, it seems more in keeping with Vader's character and motivation to have him make the first move, as it were.
