yeah, think so....notice i said star destroyer scene, not death star scene....pretty sure there's a scene with vader, palpatine and tarkin looking out the window of a star destroyer somewhere near the end of the film....whether they're watching construction commencing on the death star is still open to debate....will end on obi i think....
I think that it will be Vader, Emperor, and Tarkin staring out into the very VERY beginnings of Death Star construction from a Model Close to a Star Destroyer, (The music will build up to the empire type music! very intense, Empire music) then it will suddenly go silent and very very soft Skywalker music will play as Obi Won hands Luke to his uncle, and walks off into the desert in the twin sunset looking defeated and sad then let one note from the Skywalker Theme hang and then.....BA DA BA DA BADADADA DU DU< DUN DUN DUN< DU DU you know
that scene is in, it also involves anakins force tantrum when he finds out the truth about certain events....but following this is a certain amount of the exposition of how yoda and obi wan get to where they are in anh (i'm not sure how much is before and how much is after the scene)....then you see suited vader again aboard a star destroyer, with palpatine and tarkin (oh yes!!!).....also obi wan walking into the sunset(s) after having dropped off luke with the lars.....
official word has suited vaders screen time at about 5 mins....but they're still editing and shooting, so that could well change....
