Now if, like me, you've spent most of the last five days poring over the new Star Wars 7 trailer - and if not, why not? - then you've probably already got your own theories about just what every single detail of the thing means - and especially what it can tell us about Star Wars Episode VII: The Force Awakens itself.
What, though, if we've all missed something.
Well, if ABC News is to be believed, that's exactly what's happened. As part of a segment on Good Morning America, they revealed that the lightsaber sound at the very end of the trailer...
...is actually the sound of Luke's original lightsaber, from way back in Episode IV: A New Hope.
You can hear the two side by side in the original report below, right around the 2:19 mark:
Now - that's a pretty cool Easter egg in an of itself - I mean, I'm a sucker for a bit of original trilogy referencing after all - but it might also be part of something a whole lot bigger, too...
After all, if that's Luke's Lightsaber, that might just mean that...
A Very Particular Rumor is True
Specifically, that one that did the rounds a few months back that suggested that Episode VII's plot would hinge on the discovery of Luke's original lightsaber by Daisy Ridley and John Boyega's characters.
The reason that's kind of a big deal?
That's the lightsaber that Darth Vader sliced off in Cloud City, right at the end of The Empire Strikes Back...
Which, according to that rumor, eventually finds its way to Tatooine, and leads Ridley and Boyega's characters to run into Han, Chewie and the Millennium Falcon - and for space operatic adventures to ensue.
So, that lightsaber sound might just be key to the whole movie, then - but is that all it can tell us?
Well, maybe not...
After all, if Ethan Anderton over at FirstShowing is right...
The New Crossguard Lightsaber Might Be Involved Too
Tell you what - take another watch of that new Star Wars 7 trailer, and this time, listen out for the noise that new lightsaber makes when it ignites.
It's rougher, huh? Almost weaker than usual - with a distinct crackle to it. It sounds as though it was made by someone who had a vague idea of how to make a lightsaber, but didn't really know what they were doing.
So, Anderton's theory is essentially this: that the film's title, [Star Wars: Episode VII — The Force Awakens](movie:711158), doesn't just refer to a new Jedi being found - it suggests that the force has been dormant for the whole gap between Return of the Jedi and the new movie. The awakening of the force, then, as the trailer's voiceover suggests, would be not only one individual, but a return of the force to the galaxy:
"There's been an awakening...have you felt it? The Dark Side...and the Light."
Which Means Luke's Lightsaber is Incredibly Important
After all, in that context, Luke's original lightsaber could be the last source of old Jedi knowledge when it comes to making a new one - and therefore a major target for whichever Dark Side user has built that red lightsaber from the trailer. After all - it was Anakin Skywalker (and therefore Darth Vader)'s originally...
All of which suggests that the movie will feature - as a large part of its plot - Han, Chewie and the new kids being chased around the galaxy by a Sith menace.
