he's gonna be mentioned definately but he thinks star wars is bellow him. (and K-19 was pure gold, geez~ what a sad sack!). I've heard one rumor about how they'll explain the whole ghost thing without him, also creating a weird Palpatine/Dooku/qui-gon connection but i only heard it from one source. The rumor is awsome though
no, definitly not. It basically states that [spoiler] playing on anakins grief over his mother and the promise he made to padme on tatooine, the emperor promises anakin that he can show him a way to cheat death and that qui-gon has already done this. He then explains the ghosts and spirits of the jedi. this promise is later broken when padme dies, which is why palpatine is not spared any of anakin's wrath during his big "force explosion"[spoiler]
