You know, I'm not actually looking forward to it one bit. I'd much rather they kept the EU and made some movies based off that, like the Thrawn Trilogy. I've read some leaked info and the movie seems...bad. It compromises some very important things about the lore, in my opinion. And it keeps pushing the "two separate sides of the force" approach which I think is a load of bantha...faecal matter.
Also, from a technical point of view, that lightsaber is absolutely ridiculous. I do like the CGI on it, but aside from that it's rather stupid. I like to think I know a bit about lightsabers so hear me out 
Now, I didn't know this, but Tabaet pointed out to me that when lightsaber blades collide, their magnetic field locks them in place there. They can't slide. So already, the crossguard is a bit pointless. But let's assume that they retconned that too. Let's say the blade is sliding down the sith's blade. What does it hit? The protruding emitter. Not the lightsaber crossguard. It hits the emitter. It cuts the emitter off. Along with several fingers I'd imagine. Pointless, just pointless I tell you.
One thing I did like was the shot with the X-Wings. That looked pretty cool. But I won't be seeing the movie. Or at least, I won't be paying to see it. I choose to believe that the EU still exists!
Also, you are assuming the metal used in the hilt is cuttable. Which, considering how you are a proponent of the former EU, you might remember is not necessarily true. Some materials, including metals, in the SWU are resistant or even impervious to a lightsaber blade. So.... there's that....
Personally, I can't wait for this movie. And I'm going to be the opposite of you because I am excited BECAUSE they eliminated the EU.
The EU was so expansive and so overwhelming that it diluted the story. There was too much. There were too many stories and novels and so on that every character had every moment of their lives accounted for. There was no room for creativity. No way could they make a movie AND keep the EU. I know what you may say; "They could have made the EU into movies! They make books into movies!"... And you'd be right... But, if we're being honest... a lot of the EU is just bad.
I hope it exceeds your expectations and you have an enjoyable time, though. I'm just glad someone is DOING something with the series. I expect the first movie to be fanservice. Lots of callbacks and introductions. 2nd movie is the critical one, IMO. 2017, come faster!
