Obviously this is what he would have said if the petulant Vader hadn't then struck him down.....just shows you should always let people finish speaking. Infact that whole conversation doesn't fit after seeing RotS. The following would be better; DV: "You tried to kill me and left me on planet full of molten hot Magma you s-- of a b----" OK: "Errrrm" DV: "Now I am the master (well not in a Sith way, but best not tell him that)" OK: "Only a master of evil" DV: " (at least he doesn't know i'm NOT the master)What've you been doing for the past 19 years?" OK: "Not much just hiding (can't mention Tatooine or his son really), if you strike me down i'll become more powerful than you can imagine!" DV: "How much power do you think i can imagine, we're on a space station the size of a small moon that's pretty powerful infact we just destroyed Alderaan, the distubance in the force it caused was pretty powerful" Fight commences, Vader strikes down Obi-Wan and his body vanishes. Vader looks puzzled. Later as they are waiting for the Death Star to reach Yavin IV, Vader starts thinking what happened to his body, wonder if he became a ghost? How'd he do that? I'll build a meditation chamber and think about it!!
