The logistics of the ending sequence don't really make a lot of sense if you think about it. Bail trusted Leia to go get Obi-Wan, but then why is she in the Tantive IV riding piggyback on the flagship going into the middle of the battle?
Then there's the whole "this a consular ship, we're on a diplomatic mission" line in ANH when like 15 minutes earlier Vader was slaughtering Rebels as they got the plans to the ship, and then he saw them leave. I don't think he's going to buy that one Antilles.
Don't get me wrong, it was a cool sequence, and it didn't really detract from the movie for me, but they could have maybe made the direct connection to ANH a little smoother.
