Mirroring in Episode 3
I've noticed a few similarities, I'm sure you guys have seen others as well.
Based on the pics released the flight formations of the star fighters in the ROTS are similar to the ones from A New Hope and Return of the Jedi.
The last duel with Dooku has similarities with the duel in Return of the Jedi. Palpatine observes as Anakin fights Dooku and instigates his execution; much like in ROTJ when he observes Darth Vader fight Luke and tries to instigate Vader's death.
Palpatine revealing his true identity with Anakin has similar elements to the scene in Return of the Jedi when Luke makes his plea to Darth Vader to escape with him on Endor. However, in ROTS, Palpatine argues with Anakin that there is an alternative to being a Jedi. Anakin even draws his lightsaber in defiance and Palpatine doesn't even flinch and continues his argument; much like Luke did when Vader was inspecting his lighsaber.
It would be ironic if the vessel used to save the critically injured Anakin was the Millennium Falcon- the same vessel that saved Luke in ESB. Although I think that this situation has already be shot down.
