Cool, but why would the movie be called "Heir to the Empire" when they already used "Empire" for V; and the Star Wars movie titles seem to reflect on actions rather than nouns; like II is not "The Clone Army" it's "Attack of the Clones"; not about the clones, but about their attack.
Something like Legacy of the Shadows is an example of a thing that'd work as it's not about Shadows (noun), but about the Legacy of it, and not a concrete noun; and since both Shadow and Legacy hasn't been used before, it's not reusing any words.
Hey guy, I dont know if you dont saw the expanded universe of Star wars, but this name is a reference from the first book of the trilogy of Admiral Trawn, a new enemy why command the last empire forces against the new republic.
Oh yeah, I just learned about it when it was announced that Episode VII was gonna be made. Many people said they want to see the Trawn Trilogy, but I heard Disney will go way into the future so they can make a whole new story for the trilogy.
If it were me, I'd want Episode VII be about retaking Coruscant in 6 ABY, then Palpatine's final death in 11 ABY, and finally the end of the war at 19 ABY. If they wanted to do another trilogy then, they could always make X, XI and XII about the Yuuzhan Vong invasion . . .
