The Nerd in Me

So by default straight edge people have to love Star Wars. It also goes in hand with the generation of most straight edge people that I know.
First a story as to why I want to discuss this.
A guy next to me had a Chewbacca ring tone which was constantly ringing. When he was off the phone I asks, "by your your ring tone I have to ask if you have seen the new trailer". Now if you are breathing and even remotely like Star War you should know what I mean by "trailer". But this guy says to me, "what trailer?" Ahhh "Star Wars" I said. He then says, "Yeah it's got this really cool new light saber." that was all he got out before Chewbacca began to ring his phone once again.
Now All I have noticed is that this "really cool new lightsaber" is really dumb, and most Star Wars nerds agree.
With that said I am here to chime in on the new teaser trailer.
I haven't seen the trailer. I refuse to pay the $20 to watch a terrible movie to watch an 80 second trailer. But like not voting and complaining about government I can still comment. In the age of Jedis can we have a more technical lightsaber than just a two dimensional weapon that looks like a medieval sword? Would a Jedi not have the ability to channel such a weapon into a multidimensional, say sphere that could not only be used to attack but as a force field to defend self and others?

OK I'm out of nerdom. 393 days till the release!
