I got my AoR GM screen today and can tell you that the tables are almost exactly the same - there are only minor differences in the weapons section.
Haven't read the adventure yet. Extra rules look solid and generally boil down to adding a blue/black die in certain situations while operating in squads or squadrons.
Just in case anyone was wondering...
It's still worth buying - Darth Vader can intimidate your players now! (or you can combine both screens to have Boba and Vader at the same time
)
