Purple... 'nuff said.
All your arguments are now invalid.
As for the saber, I have heard something that sounded VERY convincing. It was from my Philosophy teacher of all people, he went on this long explanation on why that saber is so awesome. (He spent like half an hour of our class time. XD) He is NOT one to make stuff up, he is one to know a lot about something I did not even know it was possible to know so much about... like star wars.
He claimed that there was a sabre that was like that one long ago. It was held by some very powerful guy who turned dark or was on the dark side to begin with. The name escapes me... though if someone told me I might remember. Basically the guy was the most powerful of anyone. I tried searching the internet and found nothing... all I found were a few different people who wielded cross-guard sabres. Apparently the lightsaber is some sort of relic. He also stated a bunch about how luke is now super powerful, so powerful rocks shake around him, and he has to go into hiding for most of the movie.
I can't really give evidence for this, because I don't know where he got all the info. But I know for sure my teacher was serious and thought this was for sure true. I'm posting this mainly to see if anyone knows what I'm talking about, maybe this is true but you haven't thought about it being that way? I want to see if this reminds anyone of anything. It of course could possibly be a theory of his that he thought for sure must be what the movie will be, and his theory ends up being incorrect, but at least the character and relic he talked about must be something in the comics or books or whatever.
What do you think about the saber being some sort of relic?
