Sanitized Han
I think what GL did to Han with Greedo was totally inconsistent and just plain stupid because it begs to question all the other times that Han shot first:
On the Death Star in New Hope, Han has no problem shooting an alien in the garbage heap once they were out and safe. Perhaps in the special special edition, the snakey garbage alien will have a blaster and try to shoot Han first. Han will jerk back and return fire, ala Greedo scene -- because we can't just kill an alien in cold blood.
Also, on Bespin, Han tries to shoot an unarmed Vader when they first meet. In the future edition, Boba will take a shot at him first.
Han, I'm afraid, turned incompetant in the ROTJ as someone said, (the dumbest reaction to "he's my brother," ever shown on film) but after the Greedo "improvement," Han lost even more cred as a badass smuggler.
