It will be come December
I've been thinking about this. Will the general Star Wars fans care about first appearances? Sure, I imagine more interest in the comics when the new movie hits, but will a specific issue (other than #1) command any sort of premium for that crowd? Assuming there's no character or theme carried over into the new movies, I don't see any one issue rising above the rest.
This would be a true 1st appearance, even before they show up on film. And with the flood of Star Wars media Disney is about to unleash on us for the rest of our lives, sooner or later these characters will pop up on screen.
its hard to believe there would be ZERO impact on the comics.
That's what I'm saying though. If the Star Wars community at large is to create an impact on a specific issue, that character would need to appear outside of the comics.
Absolutely, it's a coin flip, they either appear in a movie or they don't. But, If they do though, look out. 3 First appearances with an 85K run. Even if just the droids show up unnamed, I think there's a winner here.
