Don't forget we also saw Qui-Gon's body being cremated in The Phantom Menace and then he popped up as a ghost in The Clone Wars. In fact he's supposed to be the one who taught Yoda how to become a Force Ghost, and Yoda taught Obi-Wan.It did seem more like what happened to Obi-Wan (gone before Vader even struck him), than Yoda (dies, then disappears.)
Gotta wonder if that disparity ever caused some fanboy aneurisms back in the day. Especially when you throw in that we also see Anakin die and then become a ghost, but it’s never even hinted that his corpse vanishes at all.
I can't help but wonder if they still would have killed Luke if they knew that Carrie Fisher was going to die. I'm definitely expecting him to pop back up as a Force Ghost in Episode IX, just so we can get at least one more movie with a direct connection to the Original Trilogy.I hope Force-ghost Luke shows up at some point in Episode IX.
