I expected to be much more excited after watching the teaser, because that's usually how those things go. As it stands... it's decent as bait, I guess, it ticks the boxes you'd expect it to tick and that's kind of it. Not that crazy about it, frankly. So far it feels a bit... new-ish? I don't get the 'used' feel I got from the OT from what they've shown here. It's a bit shinier than that. Doesn't seem sterile, thankfully.
All in all it changed nothing for me. Which I find somewhat puzzling.
edit: Oh, yeah, and the new lightsaber does indeed look pretty stupid. If it is a hilt (and it sure looks like one for the time being) it's a terrible design choice for it to be lazers. Everything's better with lazers, I know, but adding lazers to the part that you hold your sword with is probably the only thing lazers won't improve.
Lazers!
