Spoiler & Possible Rumor:
The Blockade Runner from Star Wars: A New Hope is definitely the one we'll see in Episode 3, though it'll be much cleaner and not so worn down as you may remember it. It is indeed the ship Bail Organa travels on to Alderaan at the end of the movie. It is even complete now including landing gear - it's been slightly redesigned, just to make it look a little fresh and new compared to what we see in the original film.
Escape pods from this craft are also seen and used in the film. This ship is Bail Organa's to use throughout the film - it definitely has a "newer" look to it. There's also a good chance you'll see a scene that takes place on the never before seen bridge of the Tantive IV, and you'll see that it is capable of making planet-side landings with those new gear.
Palpatine and Sidious are the same person. The dark side shrouds everything, even Jedi eyes.
The new bad guy is the leader of the droid armies. He is the ultimate Jedi-killing machine. He isn't 100% droid but dont' expect his backstory to be revealed in the film. His backstory will be explained as much as Darth Maul's was in Episode I.
Anakin kills Dooku, and really early in the film as previously reported. And the former Jedi isn't officially named "Darth Vader" until after the lava bath. But don't take this to mean he doesn't do some very very dark things before the duel takes place.
