Yeah the William Gibson Alien 3 hardcover was one of the things I ordered in my recent "I should pick these up sooner rather than later" Dark Horse mini-spree, and it's a shame that just as they were getting into these new comics based on unmade or alternate versions of films they got cut short.
I was really hoping that between that and the Alien and Predator Unproduced Screenplays this was going to be the beginning of a new offshoot of these kinds of adaptations of "lost" material, but yeah I guess the most we can hope for now is that at some point down the road Marvel sees value in putting out stuff like this too.
I wouldn't expect it to be for a long time though seeing as I'm sure they'll want to firmly establish their regular Alien and Predator comics universe firsts (plus the inevitable crossovers, of course), but maybe one day.......one day.....
