Humans will win most likely, with predators coming in close second, and while I have not read this book you speak of, I have read the comic series from looong time ago when I was a kid, and let me just say that an alliance between 2 of the species is not that far fetched.
But from everything I have read they are not using any of the original comics story lines hardly at all, except the most basic premise. Which is a shame really, cuz the original comic mini-series had a really great storyline, much better than what I have been hearing about this movie.
But I'm still uber-excited to see it, and will prolly lay out of work opening night lol.
