I gotta say, I find it kinda strange that after years of Dark Horse apparently being unable to collect stuff like Countdown and the film adaptations, the moment Marvel get the license they're in an omnibus lol.
Hopefully the presence of those stories is a sign they're actually going to be collecting everything. As someone who's not really into comics but has always thought about getting the Alien/Predator titles - partly out of curiosity, but mostly for the sake of completing my collection - this would be such a good opportunity I really couldn't pass it up.
